direct combustion of shell material is easier and less time consuming than acidification. In museum collections bivalve shells are traditionally dry stored, whereas soft tissues are preserved in 70% ethanol, sometimes after fixation with 10% formalin. However, often the whole animal is preserved in ethanol and shells are not stored separately. For the application of these preserved specimens in the investigation of past d N values it is essential to know if liquid preservation methods have an effect on the d N values of bivalve shells and if this effect is predictable. The effects of liquid preservation on the d N values of biological tissues have been examined in a variety of For testing the in uence of CaCO 3 content on d N measurements, different mixtures of acetanilide with inorganic pure CaCO 3 were made, containing between 0 and 10.

4 weight % N. Powder calcite samples were loaded into 4 _ 6 mm tin cups and weighed. d N values were measured using an elemental analyzer coupled via a CONFLO III to a ThermoFinnigan Delta V t isotope ratio mass spectrometer. An inline soda lime CO trap was used to scrub MLN8237 CO 2 from the gas stream entering the gas chromatography column of the EA. IAEA N1 was used as a standard, with an accepted value of 0. 4 _ 0. 2% Long term. standard reproducibility is better than 0. 1% for samples nature, even samples between 5 and mg N provided reasonable data. There is also an upper limit to the amount of shell material that can be loaded into the EA, but this was not evaluated here.

This method is robust because calcium carbonate com pletely decomposes around 8258C and the ash combustion Nilotinib in the EA was around 10208C, therefore, all N should be released from the matrix and carried to the IRMS. Moreover, previous studies have used an EA IRMS system to combust Fig. 2 that the narrow and near symmetrical peak shapes are similar for both shell carbonate and synthetic mixtures, which suggests that both matrices are reacting similarly in the EA IRMS. We therefore argue that it is possible to measure carbonates for d C analysis. It is clear from the traces in larger than 30 mg N. d N values are expressed in % vs. atmospheric nitrogen. Pure synthetic CaCO 3 had peaks similar to empty tin cups, empty tin cup 1/4 0. 49 Vs) and therefore did not contribute much to the calculated delta values. The acetanilide standard had a d N value of 2.

12 _ 0. 13% when it was run without PI3K Inhibitors synthetic CaCO 3 and was _2. 02 _ 0. 11% when it was run with 98. 4 to 66. 8% CaCO 3. These values are not significantly different. In addition, during a preliminary trial, we ran 0. 4 mg of the IAEA N1 ammonium sulfate SO 4) standard in. 72 mg CaCO 3 and found no offset from N1 standards run without CaCO3. Our results show that samples with as little as 20 mg N can provide accurate d N values. Prior acidification is not required to eliminate the carbonate matrix to produce accurate results, as has been previously reported. It should be noted that mollusks with very low organic matrix in their shells may require a pre concentration step to reduce the poorer precision of small samples. However, considering the large fractionations associated with nitrogen isotopes in Figure 1.

Mass Spectrom. 2011, 25, 675 680 Letter to the Editor tissue is subject to metabolic turnover and is thus repre sentative for a specific time window, see e. g., Paulet et al,. while the shell samples averaged at least 1 year of growth. This makes comparing soft tissues with shell organic matrix difficult. However, as shown in Delong and Thorp, tissues with slower turnover rates, such as the adductor muscle, are better for comparisons with metabolically inactive shells.

Most previous studies that report differences between skeletal d N and soft tissue d N do not take the different amounts of time being averaged into consider ation. Moreover, HSP many studies compare whole body tissue d N data to shell data while it is known that different organs can have quite different d N values, sometimes as much as 5% in the same animal. This may explain why Dtissue shell values for the same species of clam range from 0. 2 to 2. 4%, see ODonnell et al.. Soft tissue d N data from M. edulis specimens collected at three different periods in 2002 from Knokke show significant changes throughout the year, which would be averaged in the shell samples we analyzed. Taking the average of these 25 soft tissue data results in a Dtissue shell value of _1. 5 _ 1. 0%. In the future it is important to compare tissues and shells that represent the same time period.

The recommended dose is yet to be established Two candidates from Pfizer are currently being developed, one for i.v. administration, and one for oral dosing PF 05212384.

Dose escalation is ongoing for both compounds 5.3. p110??Selective PI3K Inhibitors The potent p110??specific inhibitor CAL 101 exhibits 40 to 300 fold selectivity for that particular isoform, as compared to other PI3K enzymes and is undergoing Phase I clinical evaluation in relapsed or refractory haematological malignancies.

The first interim reports from phase I trials with CAL 101 show promising drug activity and a lack of severe toxicity in haematological cancer patients. Plasma exposure was shown to increase with dose. AKTTHR308 as a marker of PI3K activation was measured AZD8931 in cells from a subset of chronic lymphocytic leukaemia patients with circulating lymphocytes and was observed to be reduced by 90% following dosing, demonstrating target inhibition. 6. SUMMARY AND FUTURE PERSPECTIVE As mentioned earlier in this review, the progression of PI3K inhibitors over the last twenty years or so has been remarkable. There are a number of interesting and important features that can be highlighted.
First is the evolution from chemical tool compounds, like LY294002 1, Wortmannin 2 and PI 103 18, to drugs that are now beginning to show pharmacodynamic evidence of target modulation and clear signs of therapeutic benefit to cancer patients. Next to highlight is the impact of the crystal structures of p110 catalytic domains, facilitating the interpretation of isoform selectivity profiles and the prospective design of desired profiles. In the landmark study by Knight et al, common selectivity combinations were identified, as with agents that exhibit preferences for p110??p110???and p110??????? Inhibitors of p110???often also inhibit the class IV isoforms DNAPK and mTOR, as with PI 103, but it has been possible to remove the class IV inhibition from class I selective inhibitors as in case of GDC 0941 3 compared to PI 103.
The desirability of p110??pan class I isoform selectivity for cancer therapy is still being debated. It is now clear that highly selective inhibitors of p110???can be produced and that p110??????inhibitors can also be obtained, for potential use in inflammation. Many variations on these core patterns exist. Although mouse models will help, it is likely that the preferred isoform selectivity profiles for medical use, as distinct from chemical tools, will only emerge following detailed clinical evaluation of multiple agents. For future drug design, the SAR rules for achieving selectivity are progressively being defined, facilitated by the increasing availability of crystal structures.

IR spectra of the polycrystalline samples of D PAM, dispersed in the KBr pellets, measured at two diferent temperatures and in the N_H and N_D ranges. found, no general diferentiation of the polarization properties of the two opposite spectral branches of the N_H band occurs. Therefore, the PAM crystal spectra in regard to these properties fairly resemble significantly the spectra of N methylthioacet amide and acetanilide crystals measured earlier. In Figure 6 IR spectra of polycrystalline samples of PAM, N methylthio acetamide, and acetanilide, measured in the frequency range of the N_H band, are shown. 3. 4. Isotopic Dilution Effects in the Crystalline Spectra. Replacement of protons by deuterons in the hydrogen bonds of PAM crystals causes the appearance of a new band in the 2300_2500 cm range, attributed to the N_D bond stretching N_D ).

In Figure 7 IR spectra of partially deuterated polycrystalline samples of PAM, measured in the vibrations the ac plane, 60% D PAM and 40% PAM, the ab plane, 60% D PAM and 40% PAM. vector of the incident beam of the IR radiation with respect to the oriented crystal lattice. The observed homogeneous linear dichroic properties of the crystalline spectra LY294002 in the N_D band range prove that the band consists of only one spectral branch. It remains in an approximate relation by the 2 factor with the frequency of the higher frequency branch of the residual N_H band. Next the almost homogeneous polarization properties of the residual N_H band were also measured. The shape of the band remained practically unchanged in spite of the replacement of the major part of the hydrogen bond protons by deuterons.

The residual N_H bands of the two crystal forms remain unchanged while the correspond ing bands of the isotopically Maraviroc neat crystals difer to some extent. 4. 1. Choice of Model forthe Spectra Interpretation. Wewill show that all the discussed spectral properties of the PAM crystals can be quantitatively described in terms of a model by assuming that a centrosymmetric dimer of the N_H 3 3 3 O hydrogen bonds is the bearer of the basic crystal spectral properties. This means that from a unit cell of a crystal the model selects only those translationally independent pairs of hydrogen bonds that are most strongly exciton coupled. The exciton coupling involves the pairs of the N_H 3 3 3 O hydrogen bonds that are connected with the symmetry center inversion operation.

Moreover, each hydrogen bond belongs to another, translationally nonequivalent chain of the associated molecules. Indeed, such dimeric systems of the hydrogen bonds are considered responsible for the isotopically diluted crystal spectra. The relatively weak exciton coupling in the unit cell, involving these two translationally nonequivalent dimers are only responsible for GPCR Signaling the negligibly small splitting of the spectral lines. This effect differentiates the spectra measured for the two different crystallographic faces. These latest fine spectral effects seem to be attributed to the couplings seem to concern the adjacent hydrogen bonds in each chain.

Then we will prove that the contour shapes of the residual N_H and N_D bands can be quantitatively reproduced by the model calculations based on the formalism of the strong coupling theory of the IR spectra of a centrosymmetric dimeric hydrogen 6_8 bond system. 4. 2. Model Calculations of the N_H and N_D Band Contour Shapes. Model calculations, aiming at reconstituting the residual and band DNA Damage shapes, were performed within the limitsofthestrong coupling theory, foramodelcentrosymmetric N_H N_D 6_8 N_H 3 3 3 main O hydrogen bond dimeric system. We assumed that the N_H and N_D band shaping mechanism involved a strong anharmonic coupling, including the high frequency proton stretching vibrations and the low frequency N 3 3 3 O hydrogen bridge stretching vibrational motions. According to the consequences of the strong coupling model for centrosymmetric.

The N_H band from the PAM band shape simulation PARP in the limits of the strong coupling model: the plus dimeric band reconstitut ing the symmetry allowed transition band, the minus dimeric band reproducing the forbidden transition band, the superposition of the plus and minus bands with their statistical weight parameters N_D band from the band shape simulation in the limits of the strong coupling model: the plus dimeric band reconstituting the symmetry allowed transition band, the minus dimeric band reproducing the forbidden transition band, the superposition of the plus and minus bands with their statistical weight parameters Ft and F_ taken into account. The corresponding experimental spectrum treated as a superposition of two component bands. They corre sponded to the excitation of the two kinds of proton stretching vibrations, each exhibiting a different symmetry. For the C i point symmetry group of the model dimer, the proton totally symmetric in phase vibration normal coordinate belongs to the A g representation when the nontotally symmetric out of phase vibration coordinate belongs to the A u represen tation.

These newly isolated organisms will allow us to obtain a better understanding of the biochemistry and genetics of acetanilide herbicide catabolism by microorganism and will provide new tools for the bioremediation of environments affected by these herbicides. MATERIALS AND METHODS Chemicals. Metolachlor was a gift from Syngenta Crop Protection, Greensboro, NC. Uniformly ring labeled metolachlor was graciously supplied by Syngenta Crop Protection. Acetochlor and alachlor werepurchased fromChemService. Uniformlyring labeled alachlor was gra ciously supplied by Monsanto Corp. The metolachlor standard for LC MS analysis was obtained from Chem Service. Stock solutions of metolachlor, acetochlor, and alachlor were prepared in water and stored at 4 C until used.

All Apoptosis other chemicals were obtained from Fischer Scientific, Pittsburgh, PA. Growth Conditions and Isolation of Microorganisms. Silty clay soils from Spain, which had 10 and 2 year histories of metolachlor and S metolachlor application, respectively, were used in this study. These soils received 3. 75 kg/ha of metolachlor once per year. Microorganisms were obtained from the soil following enrichment for 5 days inminimal medium using metolachloras the sole sourceof C for growth. The metolachlor was added after autoclaving,and the pHwas adjusted to 7. 0. The same procedure was used for media containing acetochlor and alachlor. All of the experiments were conducted at 30 C, because the isolated yeast had difficulties growing at lower temperatures. Cultures were incubated for up to 3 days, and microorganisms were isolated using a dilution plating technique and by picking isolate colonies.

Presumptive metolachlor degrading microorgan isms were restreaked for purity, several times, Angiogenesis on the same medium and examined microscopically following gram staining. The MM was amended with 0. 04% yeast extract, 0. 05% sucrose, or both to enhance the growth of microorganisms at the beginning of the exponential phase of growth. Microbial Identification. DNA was extracted from bacterial and yeastcellsbyusingafreeze thawandsonicationtechnique. Forthebacteria, the 16S rRNA gene was amplified by PCR using universal bacterial primers 8F 5 GAGTT and 92R 5 TACCTT as described by Polz and Cavanaugh. These primers were also used for sequencing. For the yeast, three different regions of 18S rRNA were amplified and sequenced.

The universal fungal primers 1F 5 AACCTGGTT and 1772R 5 TGATCCTT were used for the amplification and se quencingofthe 18S rRNAgene. The sequences ofthe ITS1 5. 8S ITS2 regions were determined using primers ITS1 and ITS4. Primers NL1 5 CATATCA and NL4 CFTR 5 GTCCGTGT were used for amplification of the D1/D2 seg ment of 26S rDNA. PCR reactions were carried out using an iCycler thermocycler, using different protocols depending on the primers used. For the 16S amplification, an initial denaturation step of 3 min at 94 C was followed by 35 cycles of amplification consisting of 1 min at 94 C, 1 min at 50 C, and 2 min at 72 C. For amplification of 18S rRNA gene samples were denatured for 10 min at 95 C, followed by 30 cycles of denaturation at 95 C for 15 s, 15 s at 50 C, and elongation at 72 C for 2 min, with a final extension step of 10 min at 72 C.

c-Met Signaling Pathway The ITS region was amplified using ITS1/ITS2 primers and an initial denaturation step of 10minat95 C. Thiswas followedby30cyclesofdenaturationat94 Cfor 30 s, 30 s at 58 C, elongation at 72 C for 30 s, and a final extension step of 10 min at 72 C. For amplification of the 26S rRNA gene with NL1/NL4 primers, the reaction was initiated with an initial denaturation at 94 C for 10 min. This was followed with 36 cycles of 30 s at 94 C, 30 s at 52 C, and 1 min at 72 C, with a final extension at 72 C for 5 min. DNA sequencing was done at the University of Minnesota BioMedical Genomics Center. All PCR products were purified by using a QIAquick PurificationKit priortosequencing. Sequences were analyzed with Applied Biosystems Sequence Scanner software v1.

0 and were assembled HSP by using Clustal W2. Sequence identity was determined by using BLAST. Species identification was obtained by using BLAST, sequence match software of the Ribosomal Database Project RDP II and the CBS Yeast Database. Additional biochemical tests were performed to more accurately assign species status to the isolated yeast. The yeast was grown in the presence of a discriminatory carbon source, in MM containing glucose, sucrose, D xylose, trehalose, maltose, starch, rhamnose, galactose, inositol, lactose, D arabinose, or D mannitol. Plateswereincubatedat30 Cinthedark, and growth was recorded 24 96 h after inoculation. Microbial Growth. The influence of metolachlor on the growth kinetics of the isolated yeast and bacterium was determined. Cells were grown at 30 C in 250 mL flasks containing 100 mL of MM medium and 50 g mL metolachlor, pH 7. 0, with or without 0. 05% sucrose, 0. 04% yeast extract, or both.

Similartowhatwasfoundwith C. xestobii,ourstudies also indicate that B. simplex uses metolachlor as a sole source of C and energy for growth. However, neither microorganism had the ability to degrade some of the proposed main metabolites of metolachlor, MESA or MOA. Under aerobic conditions, only partial biodegradation of metolachlor by bacteria was previously reported, and it has been proposed that degradation proceeds through a co metabolic process in the presence of other C sources. How ever, the catabolism of metolachlor by B. simplex does not appear to be due to a co metabolic process, because it occurred in MM without other added carbon substrates and with only a single microorganism present. Despite this, the transformation of metolachlor by B.

simplex was not complete, and this may be related,inpart,totheapparentpersistenceofmetolachlorinsoils. Forexample,inlaboratoryincubationexperimentsKonopkaand Turco reportedthatmetolachlor wasnot degraded over a period of 128 days in vadose zone samples obtained from an agricultural field. Nevertheless, our data indicate that partial PARP Inhibitors transformation of this herbicide was still sufficient to supply this bacterium with sufficient C and energy for growth. Degradation of Acetochlor and Alachlor by C. xestobii. The degradation of relatively high concentrations of acetochlor and alachlor by C. xestobii was also examined, and the disappearance of both of these substrates was also determined to be due to the result of microbial metabolism. Results in Figure 5 show that 50% of the added acetochlor was degraded by C.

xestobii in the first 15 h of growth, and the concentration decreased by 60% after 312 h. In the resting cell assays, however, about 80% of the acetochlor was degraded in 15 h, but the degradation was also incomplete, and there p53 Signaling Pathway was no degradation after that time. Whereas acetochlor was previously shown to be completely degraded by a consortium of eight microorganisms after 4 days, no single isolate was able to degrade acetochlor efficiently. Results in Figure 6 show that C. xestobii also transformed ??70% of the initial concentration of alachlor after 3 days of growth, after which time degradation was much slower. In the restingcellassays,however,degradationproceededmorequickly, and ??80% was transformed after 2 days. Whereas Xu et al.

reported that 63 and 39% of alachlor and metolachlor, respec tively, were degraded by mixed microbial consortia after 21 days of incubation, C. xestobii surpassed those AMPK Signaling degradation amounts in shorter incubation periods. Control media, which were not inoculated, did not exhibit acetochlor or alachlor disappearance. A summary of the degradation of acetanilide herbicides by the isolated microorganisms is shown in Table 1. Mineralization of Metolachlor and Alachlor by C. xestobii and B. simplex. Growth of C. xestobii in the presence of meto lachlor showed that up to 25% of the ring labeled compound was converted into CO 2 after 10 days of growth. Like catabolism, the mineralization of metolachlor by C. xestobii was not complete, and no further mineralization occurred even after 360 h of incubation.

Interestingly, mineralization of metolachlor in MM amended with yeast extract was greater than that seen in MM containing only metolachlor. In the former case, PLK miner alization started after 4 days of incubation and reached only 6% after 240 days of incubation, whereas mineralization started 24 h earlier in resting cells assays, indicating a direct relationship between cell numbers and mineralization rate. Growth of C. xestobii in the presence of alachlor showed that up to 20% of the ring labeled compound was mineralized to CO 2 after 48 h. After that time, mineralization proceeded much more slowly, and 40% was transformed after 336 h of incubation. Whereas white rot fungi were previously reported to The colored product was not seen in NaOH vials in control uninoculated biometer flasks containing alachlor or metolachlor mineralization studies.

Whereas B. simplex has the ability to use metolachlor as the sole C and energy sources for growth, the bacterium failed to mineralize this herbicide, at least the C ring labeled PARP atoms. This indicated that B. simplex likely uses a different degradation path way for metolachlor than does C. xestobii. In some ways, this result is similar to those reported by Saxena et al., who failed to isolate bacteria that could mineralize metolachlor. However, these authors did report that strains of Bacillus circulans, Bacillus megaterium, and an actinomycete were able to transform metola chlor into several metabolites. Although Stamper and Tuovinen postulated that miner alization of metolachlor may not be the major route for its dissipation in natural systems, results are currently contradictory. For example, Staddon et al. reported that 4% of metola chlor was mineralized after 46 days, but Krutz et al. reported that 40% of metolachlor was mineralized after 63 days in a soil.

It showed a low potential detection of glucose with high sensitivity, low detection limit, good reproducibility, long term stability, fast response, and high specificity. This biosensor was applied in the determination of glucose in real blood and urine samples with satisfactory results. Yang et al. prepared MWCNTs composite using Pt NP doped sol/gel solution as a binder and incorporated ZSTK474 GOx for glucose biosensor. The sensitivity enhanced 4 times when Pt nanoparticles were loaded. A glucose biosensor, developed by Rivas and co workers was based on the electrocatalytic activity of copper and iridium microparticles incorporated within the CNTs paste electrode containing GOx. This biosensor detected glucose at very low potentials with high sensitivity and selectivity. Yao and Shiu examined the electrochemical and electrocatalytic properties of different types of CNTs material and used them for fabricating glucose biosensors.
They found Brivanib that the electrodes modified with SWCNTs usually had better electron transfer and electrocatalytic properties than the corresponding MWCNTs modified electrodes. Recently, Jia et al. reported the fabrication of needle type glucose biosensor by packing a mixture of MWCNTs, graphite powder, and freeze dried GOx powder into a glass capillary of 0.5 mm inner diameter. It showed an improved sensitivity and stability when the experimental condition was optimized. Zhu and co workers proposed a bienzymatic mediatorless glucose biosensor based on co immobilization of GOx and horseradish peroxidase in an electropolymerized PPy film on a SWCNTs modified electrode. They took advantage of direct electron transfer characteristics of HRP with CNTs electrode and realized a lower operational potential for selective determination with a minimized interference.
The detection of hydrogen peroxide is very important because many enzymatic biosensors rely on the detection of H2O2 generated by an enzymatic reaction. Since the amount of generated H2O2 from an enzymatic reaction is very low, the fabrication of a highly sensitive H2O2 biosensor is needed. CNTs can be used in the fabrication of highly sensitive H2O2 biosensors. There have been many reports on CNTs based H2O2 biosensors. Chen and Lu reported the encapsulation of hemoglobin in the composite film of carboxylic acid functionalized MWCNTs and polyelectrolyte surfactant polymer to develop a H2O2 biosensor. Faradic response of the Hb was observed and it exhibited excellent electrocatalytic activity to reduce H2O2. Chen et al.
proposed an amperometric thirdgeneration H2O2 biosensor based on the immobilization of Hb on the nanohybrid film of MWCNTs and gold colloidal nanoparticles. A wide range of linear response from 0.21 M to 3.0 mM with a detection limit of 80 nM was obtained. Tripathi et al. entrapped HRP in an ormosil composite doped with ferrocene monocarboxylic acid bovine serum albumin conjugate and MWCNTs for a H2O2 biosensor. MWCNTs improved the conductivity of the composite film and HRP provided a fast amperometric response to H2O2. A wide linear range between 20 M and 4.0 mM with a detection limit of 5.0 M was achieved. Luo et al. developed a H2O2 biosensor with an improved performance based on the immobilization of HRP onto electropolymerized PANI films doped with CNTs. It was found that the existence of CNTs in the biosensor system could effectively increase the amount and stability of the immobilized HRP as well as the performance of the biosensor.

TNF, reported as anti influenza cytokine, has been reported to be present in ginger. WZ3146 5.1.6. Phyllanthus emblica. The Indian gooseberry is a deciduous tree of the Euphorbiaceae family. It is also known as Amlaka and Amla. In traditional Indian medicine, dried and fresh fruits of the plant are used. All parts of the plant, including the fruit, seed, leaves, root, bark, and flowers, are used in various Ayurvedic/Unani Medicine herbal preparations. According to Ayurveda, Emblica officinalis fruit is sour and astringent in taste, with sweet, bitter, and pungent secondary tastes. Methanol extract of the fruit of Emblica officinalis has potent inhibitory action against human immunodeficiency virus 1 reverse transcriptase. Emblica officinalis aqueous extracts are used in Cuban traditional medicine for their antiviral activity against Hepatitis B virus and A and B influenza virus.
The cytotoxicity of the extract was tested by means of colony forming ability and growth inhibition assays, as well as by measuring the mitotic index. Apoptosis induction AMG-208 and cell cycle kinetics were analyzed by cytofluorimetric methods. In Ayurvedic polyherbal formulations, Emblica officinalis is a common constituent, and most notably is the primary ingredient in an ancient herbal preparation called Chyawanprash, which is itself an effective adaptogen and immunity booster that could help control swine flu infection. 5.1.7. Tinospora cordifolia. Tinospora cordifolia, also called Guduchi, is a herbaceous vine of the familyMenispermaceae indigenous to the tropical areas of India, Myanmar, and Sri Lanka.
The active constituents are diterpene compounds, including tinosporone, tinosporic acid, cordifolisides A to E, syringen, the yellow alkaloid, berberine, Giloin, crude Giloininand, and a glucosidal bitter principle, as well as polysaccharides, including arabinogalactan polysaccharide. These compounds possess adaptogenic and immunomodulating properties. Picrotene and bergenin, possessing antioxidant properties have been reported from Tinospora. Tinospora cordifolia has been studied extensively for its immunomodulating activities. The active principles of Tinospora cordifolia were found to possess immunomodulatory activities and caused significant increases in IgG antibodies in serum, along with macrophage activation. Enhancement in humoral immunity, evidenced by the hemagglutination titre, along with stimulation of cellmediated immunity were observed in the leukocyte migration inhibition tests.
The plant has immense potential for use against novel H1N1 flu since it is a potent immunostimulant. 5.1.8. Mentha piperita. Mentha piperita, family Labiatae, is a herbaceous rhizomatous perennial plant widely used in Ayurveda. It contains about 1.2% 1.5% essential oil. The volatile oil, also known as menthae piperitae aetheroleum, contains 30 70% free menthol, menthol esters and more than 40 other compounds. The principal components of the oil are menthol, menthone, and menthyl acetate. Pharmaceutical grade oil, produced by distilling the fresh aerial parts of the plant at the beginning of the flowering cycle, is standardized to contain no less than 44% menthol, 15% 30% menthone, and 5% esters, in addition to various terpenoids.
