Abstract
Essential oil (EO) composition of Smyrnium olusatrum was characterised by high proportion of furanosesquiterpenes (51.66-69.35%). The leaf methanolic extract composition was found to be rich with Quercetin-O-hexoside (39.78%). Apigenin 6,8-di-Chexoside represent the major component of flower (18.2%) and fruits (18.82%). Flower extract exhibited the highest contents of total phenolic (48.97 mg GAE/g) and flavonoid (52.63 mg RE/g). The β-carotene and lycopene contents were in the order of 4.55-26.14 mg/100g, and 8.00-49.45 mg/100g, respectively. Methanolic extracts and EOs of different organs were found to possess antioxidant activities, as determined by scavenging effect, chelating activity and β-carotene-linoleic acid model system. Furthermore, Fruit S. olusatrum EO exhibited a potent inhibitory activity against Acetylcholinesterase, while the methanolic extract showed a weaker activity. The methanolic extract displayed inhibitory effects on α-amylase, whereas the EOs was not as efficient in inhibiting this enzyme. The observed level of biological activities varied depending on the specific extracts and organs studied.

Neuropeltis acuminata (P. Beauv.): Investigation of the Chemical Variability and In Vitro Anti-inflammatory Activity of the Leaf Essential Oil from the Ivorian Species. Molecules 2022; 27:molecules27123759. [PMID: 35744884 PMCID: PMC9230793 DOI: 10.3390/molecules27123759] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 06/07/2022] [Accepted: 06/07/2022] [Indexed: 11/16/2022] Open
Abstract
The variability of chemical composition of the leaf essential oil (EO) from Neuropeltis acuminata, a climbing liana growing wild in Ivory Coast, was investigated for the first time. The in vitro anti-inflammatory activity was also evaluated. Thirty oil samples were isolated from leaves collected in three forests of the country and analyzed using a combination of Column Chromatography (CC), Gas Chromatography with Retention Indices (GC(FID)), Gas Chromatography-Mass Spectrometry (GC-MS), and 13Carbon-Nuclear Magnetic Resonance (13C-NMR). Fractionation by CC led to the first-time isolation from natural source of δ-cadinen-11-ol, whose structural elucidation by one dimension (1D) and 2D-NMR spectroscopy is reported here. Finally, 103 constituents accounting for 95.7 to 99.6% of the samples’ compositions were identified. As significant variations of the major constituents were observed, the 30 oil compositions were submitted to hierarchical cluster and principal components analyses. Five distinct groups were evidenced: Group I, dominated by (E)-β-caryophyllene, kessane, and δ-cadinene, while the main constituents of Group II were germacrene B, ledol, α-humulene, (E)-γ-bisabolen-12-ol, and γ-elemene. Group III exhibited guaiol, germacrene D, atractylone, (E)-γ-bisabolen-12-ol, δ-cadinene and bulnesol as main compounds. Group IV was dominated by (E)-nerolidol, guaiol, selina-4(15),7(11)-diene and bulnesol, whereas (E)-β-caryophyllene, α-humulene and α-muurolene were the prevalent compounds of Group V. As the harvest took place in the same dry season in the three forests, the observed chemical variability could be related to harvest sites, which includes climatic and pedologic factors, although genetic factors could not be excluded. The leaf oil sample S24 behaved as a high inhibitor of LipOXygenase (LOX) activity (half maximum Inhibitory Concentration, IC50: 0.059 ± 0.001 mg mL−1), suggesting an anti-inflammatory potential.

Abstract
The chemical variability and the in vitro anti-inflammatory activity of the leaf essential oil from Ivorian Isolona dewevrei were investigated for the first time. Forty-seven oil samples were analyzed using a combination of CC, GC(RI), GC-MS and 13C-NMR, thus leading to the identification of 113 constituents (90.8-98.9%). As the main components varied drastically from sample to sample, the 47 oil compositions were submitted to hierarchical cluster and principal components analyses. Three distinct groups, each divided into two subgroups, were evidenced. Subgroup I-A was dominated by (Z)-β-ocimene, β-eudesmol, germacrene D and (E)-β-ocimene, while (10βH)-1β,8β-oxido-cadina-4-ene, santalenone, trans-α-bergamotene and trans-β-bergamotene were the main compounds of Subgroup I-B. The prevalent constituents of Subgroup II-A were germacrene B, (E)-β-caryophyllene, (5αH,10βMe)-6,12-oxido-elema-1,3,6,11(12)-tetraene and γ-elemene. Subgroup II-B displayed germacrene B, germacrene D and (Z)-β-ocimene as the majority compounds. Germacrene D was the most abundant constituent of Group III, followed in Subgroup III-A by (E)-β-caryophyllene, (10βH)-1β,8β-oxido-cadina-4-ene, germacrene D-8-one, and then in Subgroup III-B by (Z)-β-ocimene and (E)-β-ocimene. The observed qualitative and quantitative chemical variability was probably due to combined factors, mostly phenology and season, then harvest site to a lesser extent. The lipoxygenase inhibition by a leaf oil sample was also evaluated. The oil IC50 (0.020 ± 0.005 mg/mL) was slightly higher than the non-competitive lipoxygenase inhibitor NDGA IC50 (0.013 ± 0.003 mg/mL), suggesting a significant in vitro anti-inflammatory potential.

Abstract
The growing use of herbal medicines worldwide requires ensuring their quality, safety, and efficiency to consumers and patients. Quality controls of vegetal extracts are usually undertaken according to pharmacopeial monographs. Analyses may range from simple chemical experiments to more sophisticated but more accurate methods. Nowadays, metabolomic analyses allow a fast characterization of complex mixtures. In the field, besides mass spectrometry (MS), nuclear magnetic resonance spectroscopy (NMR) has gained importance in the direct identification of natural products in complex herbal extracts. For a decade, automated dereplication processes based on 13C-NMR have been emerging to efficiently identify known major compounds in mixtures. Though less sensitive than MS, 13C-NMR has the advantage of being appropriate to discriminate stereoisomers. Since NMR spectrometers nowadays provide useful datasets in a reasonable time frame, we have recently made available MixONat, a software that processes 13C as well as distortionless enhancement by polarization transfer (DEPT)-135 and -90 data, allowing carbon multiplicity (i.e., CH3, CH2, CH, and C) filtering as a critical step. MixONat requires experimental or predicted chemical shifts (δ C) databases and displays interactive results that can be refined based on the user's phytochemical knowledge. The present article provides step-by-step instructions to use MixONat starting from database creation with freely available and/or marketed δ C datasets. Then, for training purposes, the reader is led through a 30 - 60 min procedure consisting of the 13C-NMR based dereplication of a peppermint essential oil.

Abstract
Plant-based aroma chemicals, constituting the essential oils play a great role as the natural flavours and preservatives in the food industries. Many of these metabolites are susceptible to degradation under heat (i.e. thermolabile aroma chemicals) which may influence the organoleptic properties of the end-products e.g. essential oil, oleoresin, dry herb, tea and packaged juice. The current review identified in total 42 thermolabile aroma and/or flavour molecules belonging to monoterpenoids, sesquiterpenoids and phenolics. The probable pathway of their degradation and its promoting conditions were also described. Degradation pathways were categorized into five major classes including oxidation, C-C bond cleavage, elimination, hydrolysis and rearrangement. Numerous evidences were cited in support of the thermosensitivity of these phytochemicals under pyrolytic, thermal heating or gas chromatographic conditions. Various post-harvest processes involved in the manufacturing such as drying and distillation of the crops or thermal treatment of the food-products for storage were highlighted as the root cause of degradation. The influence of thermolabile aroma chemicals to maintain the sensory quality of the end-products such as citrus juices, floral oils and thermally cooked foods was discussed in detail. In the present article, detailed insight into the chemical and sensory aspects of thermosensitive aromas and flavours was provided, covering the period from 1990 up to 2020.

Abstract
The essential oil of Eugenia uniflora has been attributed anti-depressive, antinociceptive, antileishmanial, larvicidal, antioxidant, antibacterial, and antifungal activities. It is known that the cultivation of this plant can be affected by seasonality, promoting alteration in the oil composition and its biological activities. This study aims to perform the annual evaluation of the curzerene-type oil of E. uniflora and determine its antioxidant activity. The oil yield from the dry season (1.4 ± 0.6%) did not differ statistically from that of the rainy season (1.8 ± 0.8%). Curzerene, an oxygenated sesquiterpene, was the principal constituent, and its percentage showed no significant difference between the two periods: dry (42.7% ± 6.1) and rainy (40.8 ± 5.9%). Principal component and hierarchical cluster analyses presented a high level of similarity between the monthly samples of the oils. Also, in the annual study, the yield and composition of the oils did not present a significant correlation with the climatic variables. The antioxidant activity of the oils showed inhibition of DPPH radicals with an average value of 55.0 ± 6.6%. The high curzerene content in the monthly oils of E. uniflora suggests their potential for use as a future phytotherapeutic alternative.

Abstract
INTRODUCTION Curcuma caesia (black turmeric), an essential oil-bearing rhizomatous herb has been a part of ethnomedicinal practices in India and southeast Asian countries since ancient time. Oleochemical profile of black turmeric has been investigated previously by gas chromatography coupled to mass spectrometry (GC-MS) technique from different geographical regions showing a large variation in the identity as well as abundance of the constituents. OBJECTIVES To develop an analytical method for the reliable analysis of essential oil from black turmeric rhizome through identified chemical markers and to show the credibility of the developed method on real samples. METHODS The essential oil of black turmeric was analysed through proton nuclear magnetic resonance (1 H-NMR) based method using an internal standard. RESULTS Four thermolabile sesquiterpene markers were unambiguously identified from the essential oil of black turmeric rhizome. GC-MS based analysis produced an erroneous identification of the constituents. A standardised 1 H-NMR spectroscopy based method was developed for the qualitative and quantitative analysis of the identified chemical markers. The developed method was further utilised for analysing the variation in oleochemical profile across multiple batches of harvest and the rhizomes subjected to different post-harvest storage or drying conditions. CONCLUSION The identified marker molecules and developed 1 H -NMR spectroscopic method might prove to be a useful tool for the analysis of essential oil and quality control of this endangered crop material. Also, the present study provided information on the preferred drying and storage condition of black turmeric rhizome prior to the extraction of essential oil.

However, chemo-resistance tends to occur when chemotherapy is used clinically, resulting in poor prognosis and recurrence. Currently, Chinese medicine may provide insight into the design of new therapies to overcome chemo-resistance. Furanodiene, as a heat-sensitive sesquiterpene, is isolated from the essential oil of Rhizoma Curcumae. Even though mounting evidence claiming that furanodiene possesses anti-cancer activities in various types of cancers, the underlying mechanisms against chemo-resistant cancer are not fully clear. Our study found that furanodiene could display anti-cancer effects by inhibiting cell viability, inducing cell cytotoxicity, and suppressing cell proliferation in doxorubicin-resistant MCF-7 breast cancer cells. Furthermore, furanodiene preferentially causes apoptosis by interfering with intrinsic/extrinsic-dependent and NF-κB-independent pathways in doxorubicin-resistant MCF-7 cells. These observations also prompt that furanodiene may be developed as a promising natural product for multidrug-resistant cancer therapy in the future.

Abstract
This work presents the first phytochemical investigation of Geranium kikianum Kit Tan & G. Vold (Geraniaceae), a species endemic to the southern Peloponnese, Greece. The essential oil from aerial parts of the plant was isolated by hydrodistillation and its chemical composition characterized by GC-MS. A total of 26 compounds were identified, constituting 98.3% of the oil composition. Oxygenated sesquiterpenes were the main group of constituents (75.4%). The major component of the oil was the sesquiterpene ketone germacrone (45.6%). Eleven alcohols represented the most diverse chemical class in the volatile oil (36.3%), and phytol was the most abundant acyclic diterpene alcohol (11.4%). The volatile compounds and residual water remaining after hydrodistillation were screened for their radical-scavenging activity by the DPPH method. IC 50 values ranged from 0.2±0.03 mg/mL for the undiluted decoction to 69.7±0.5 mg/mL for the essential oil. The significant antioxidant activity of the residual water, comparable with that of the widespread synthetic antioxidant BHT (0.2±0.01 mg/mL), and almost tenfold higher than thymol (1.90 ± 0.04 mg/mL), correlates with a high content of total phenolic compounds (100.2±1.7 mg GAE/g), and flavonoids (11.9±1.2 mg GAE/g).

Abstract
Among natural products, sesquiterpenes have shown promising inhibitory effects against bloodstream forms of Trypanosoma brucei, the protozoan parasite causing human African trypanosomiasis (HAT). Smyrnium olusatrum (Apiaceae), also known as Alexanders or wild celery, is a neglected horticultural crop characterized by oxygenated sesquiterpenes containing a furan ring. In the present work we explored the potential of its essential oils obtained from different organs and the main oxygenated sesquiterpenes, namely isofuranodiene, germacrone and β-acetoxyfuranoeudesm-4(15)-ene, as inhibitors of Trypanosoma brucei. All essential oils effectively inhibited the growth of parasite showing IC50 values of 1.9-4.0μg/ml. Among the main essential oil constituents, isofuranodiene exhibited a significant and selective inhibitory activity against T. brucei (IC50 of 0.6μg/ml, SI=30), with β-acetoxyfuranoeudesm-4(15)-ene giving a moderate potentiating effect. These results shed light on the possible application of isofuranodiene as an antiprotozoal agent to be included in combination treatments aimed not only at curing patients but also at preventing the diffusion of HAT.

Mechanistic and biological aspects. Fitoterapia 2017; 117:52-60. [PMID: 28069487 DOI: 10.1016/j.fitote.2016.12.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2016] [Revised: 12/11/2016] [Accepted: 12/18/2016] [Indexed: 10/20/2022]
Abstract
The industrial extraction and further applications of isofuranodiene are limited because at room temperature it spontaneously converts to curzerene, a structurally less active isomer. This work definitively identified the structure of isofuranodiene in the solid state, showing the two methyl groups in syn position. In addition, two bioactive metal cations, namely, silver(I) and copper(II) ions, were used in the attempt to obtain the chemical stability of isofuranodiene: in the case of silver(I), a labile adduct was formed, while in the case of copper(II), a more stable 1:1 adduct was achieved. In the former, the presence of silver did not significantly affect the biological activities of isofuranodiene, while in the latter, the copper(II) coordination suppressed them. The biological activities of the isofuranodiene adducts were then evaluated as antiproliferative agents against human tumor cell lines (HCT116, MDA-MB 231, and T98G). In addition, for the first time, isofuranodiene was tested as an inhibitor of DHFR (DiHydroFolateReductase) from Escherichia coli. Anticancer activity was observed in the isofuranodiene with the AgCF3SO3 adduct, in the tested cell lines, with IC50 values ranging from 4.89μM to 13.06μM, while inhibition assays highlighted a Ki of 6.22μM for isofuranodiene and of 0.17μM for the related silver adduct. Docking studies indicated a binding mode score of -6.83Kcal/mol for isofuranodiene, and an energy value of -11.82Kcal/mol for methotrexate (a classic DHFR inhibitor).

Abstract
Background Chinese medicinal herbs may use more than one species of Curcumae Radix (Yujin) is the tuberous roots of Curcumae wenyujin, C. kwangsiensis, C. phaeocaulis and C. longa. This study aimed to characterize the chemical profiles of these different species of Curcumae Radix, and develop a method for rapid discrimination of these species by ultra-high performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOFMS) combined with multivariate statistical analysis. Methods The metabolomes of 33 different batches of Curcumae Radix derived from four Curcumae species were profiled by UHPLC/Q-TOFMS. The resulting sample codes, tR–m/z pairs and ion intensities were processed by unsupervised principal component analysis (PCA) and supervised orthogonal partial least squared discriminant analysis (OPLS-DA) to characterize the chemical composition of Curcumae Radix across the four different species. Results Obvious differences were observed in the chemical compositions of the Curcumae Radix samples derived from the four different species according to PCA and OPLS-DA. These results suggested that curcumin, curcumenone, curcumenol and zederone could be used as unique chemical markers for C. longa, C. wenyujin, C. phaeocaulis and C. kwangsiensis, respectively. Conclusions This study developed a UHPLC/Q-TOFMS method coupled with multivariate statistical analysis to discriminate between Curcumae Radix samples from four different Curcumae species, i.e., C. longa, C. wenyujin, C. phaeocaulis and C. kwangsiensis. Notably, this new approach resulted in the identification of curcumin (a), curcumenone (b), curcumenol (c) and zederone (d) as unique chemical markers for the identification.

Abstract
This study examined whether the antidermatophytic activity of essential oils (EOs)
can be used as an indicator for the discovery of active natural products against
Leishmania amazonensis. The aerial parts of seven plants were hydrodistilled. Using
broth microdilution techniques, the obtained EOs were tested against three strains of
dermatophytes (Trichophyton mentagrophytes, Microsporum gypseum and Microsporum
canis). To compare the EOs antifungal and antiparasitic effects, the EOs activities
against axenic amastigotes of L. amazonensis were concurrently evaluated. For the
most promising EOs, their antileishmanial activities against parasites infecting
peritoneal macrophages of BALB/c mice were measured. The most interesting antifungal
candidates were the EOs from Cymbopogon citratus, Otacanthus azureus and Protium
heptaphyllum, whereas O. azureus, Piper hispidum and P. heptaphyllum EOs exhibited
the lowest 50% inhibitory concentration (IC50) values against axenic
amastigotes, thus revealing a certain correspondence between both activities. The P.
hispidum EO was identified as the most promising product in the results from the
infected macrophages model (IC50: 4.7 µg/mL, safety index: 8). The most
abundant compounds found in this EO were sesquiterpenes, notably curzerene and
furanodiene. Eventually, the evaluation of the antidermatophytic activity of EOs
appears to be an efficient method for identifying new potential drugs for the
treatment of L. amazonensis.

Abstract
Four sesquiterpenes were isolated from the rhizome of Curcuma xanthorrhiza Roxb.: furanodiene (1), germacrone (2), furanodienone (3), and 13-hydroxygermacrone (4). Importantly, this was the first time compounds 1 and 4 were isolated from this plant. The chemical structures of these compounds were determined using 1D- and 2D-nuclear magnetic resonance, infrared spectroscopy, and electron ionization mass spectrometry analyses. Among the isolated compounds, compounds 2 and 4 inhibited UVB-induced upregulation of the mRNA and protein expression levels of MMP-1, MMP-2, and MMP-3 in human keratinocytes (HaCaT). Moreover, this upregulation occurred in a dose-dependent manner over the range of 1-10 μM for each compound.

Abstract
INTRODUCTION Germacrenes A-C are secondary metabolites produced by various plants. They are sesquiterpene hydrocarbons bearing the (E,E)-1,5-cyclodecadiene structure known to undergo thermal rearrangement through a [3.3]-sigmatropic reaction. Such a rearrangement was evidenced by comparing the contents of a given germacrene and the corresponding elemene calculated by GC-flame ionisation detection (FID) with the relative intensities of the signals of both molecules in the (13) C-NMR spectrum of the mixture, recorded at room temperature. OBJECTIVE To develop a protocol to identify and quantify germacrenes A, B and C and in parallel the corresponding elemenes, using a combination of GC-FID and (13) C-NMR and then provide a correct analysis of Cleistopholis patens essential oils. METHODS The essential oil was submitted to GC-FID, GC-retention index, GC-MS and (13) C-NMR analyses. The relative percentages of every couple of germacrene and elemene measured by GC-FID were summed. Then, the relative ratio of the mean intensities of the signals of the protonated carbons of a given germacrene and the corresponding elemene was calculated. The contents of both compounds were obtained by combining GC-FID and (13) C-NMR data. RESULTS The true content of germacrene A/β-elemene, germacrene B/γ-elemene and germacrene C/δ-elemene in leaf and root oils from C. patens was evaluated by combination of GC-FID and (13) C-NMR data. Correct analysis of the essential oils was provided. CONCLUSION Combined analysis of essential oil including (13) C-NMR without isolation of the components, appeared really efficient to identify and quantify germacrene isomers and in parallel elemene isomers in essential oils.

Abstract
Chinese medicines (CM) have been attracting interest and acceptance in many countries. Quality control is vital for ensuring the safety and efficacy of CM. Usually, CM are used as whole plant and/or combination of several herbs, and multiple constituents are responsible for the therapeutic effects. Therefore, quality control of CM is very difficult. To date, the valid method for quantitatively evaluating the quality of CM is poor. In this article, the strategies for quantification, related to the markers, reference compounds and approaches, in quality control of CM were reviewed and discussed.

Abstract
Linalool acetate, one of the major constituent of several essential oils, is heat-labile and decomposes upon exposure to the high injector temperature during gas chromatography. Here we report the development of an improved method for detection of this compound by gas chromatography mass spectrometry (GCMS) using cold on-column injection of the sample. By using this sensitive method, it has been demonstrated that a lavandin (L.x intermedia) mutant accumulates trace quantities of linalool acetate and camphor and higher amounts of cineole and borneol compared to its parent. This plant, which very likely carries a point mutation in one or more of the genes involved in essential oil production, provides a unique tool for investigating regulation of essential oil biogenesis in plants.

Abstract
The energetics of the Cope rearrangement of 17 germacrane sesquiterpenoids to their respective elemane forms have been calculated using both density functional theory (B3LYP/6-31G*) and post Hartee-Fock (MP2/6-31G**) ab initio methods. The calculations are in qualitative agreement with experimentally observed Cope rearrangements, but the two methods give slightly different results. MP2 calculations generally show more favorable elemene energies compared to the respective germacrenes (by around 3-4 kcal mol(-1)) and smaller activation energies (by 2-3 kcal mol(-1)). Additionally, neither method is accurate enough to consistently reproduce the germacrene/elemene equilibrium. Apparently, the generally small energy differences between the two forms in these sesquiterpenoids cannot be adequately reproduced at these levels of calculation.

Abstract
A simple, sensitive and precise high-performance thin-layer chromatographic (HPTLC) method was developed and validated for the analysis of ar-turmerone and turmerone, the major constituents of the lipid soluble fraction of the herbal medicament (HM) obtained from the rhizomes of Curcuma longa (turmeric). The separation was carried out on HPTLC aluminum plates precoated with silica gel 60F-254, with n-hexane:ethyl acetate (9.8:0.2 v/v) as mobile phase. Densitometric analysis of ar-turmerone and turmerone was carried out in the absorbance mode at 254 nm. This system was found to give compact spots for ar-turmerone and turmerone (Rf values 0.5 ± 0.05; 0.6 ± 0.04, respectively). A good linear regression relationship between peak areas and the concentrations was obtained over the range of 100–600 ng/spot, with correlation coefficients of 0.997 and 0.998 for ar-turmerone and turmerone, respectively. The limit of detection and quantification was found to be 20 and 40 ng/spot for ar-turmerone and turmerone, respectively. The method was further validated for precision and recovery. The RSD values of the precision were in the range 0.49–1.33% and spike recoveries were 99.9 and 100.0% for ar-turmerone and turmerone, respectively. Analysis of different batches of HM using the above method gave ar-turmerone and turmerone contents in the range of 25–30% and 30–38%. The developed HPTLC method can be applied for identification and quantitative determination of ar-turmerone and turmerone in the lipid soluble fractions of turmeric.

Abstract
The lipid soluble fraction of curcuma longa, i.e. herbal medicament (HM) was isolated from rhizome of curcuma longa by solvent extraction method. The identification of chemical constituent present in HM was done with GC, GC-MS. The standardization of HM was done using HPLC method on the basis of three-marker compound isolated, i.e. ar-turmerone, turmerone and curlone. The effect of temperature, pH and light on stability of marker compounds of HM was studied. The composition of marker compound in HM was found to be 50-60%. The content of curcumnoids, another bioactive constituent present in HM was found to be 0.32-0.55%. The HM was found to be stable at different temperature and pH but light sensitive.

Abstract
Two neutral triterpenes and a triterpene acid were identified and quantified directly, in the absence of any purification steps, in a precipitate obtained during the industrial extraction of the leaves of Olea europaea L. using 13C-NMR spectroscopy (spectrometer operating at 4.7 T equipped with a 10 mm probe). The method was optimised in order to reduce the duration of analysis with a routine NMR spectrometer. Together with long-chain linear compounds, erythrodiol, uvaol and oleanolic acid accounted for 27.3, 18.3 and 12.5% of the precipitate, respectively.

Optimization of GC–MS conditions based on resolution and stability of analytes for simultaneous determination of nine sesquiterpenoids in three species of Curcuma rhizomes.

[PMID: 16860507 DOI: 10.1016/j.jpba.2006.06.014] [Citation(s) in RCA: 63] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2006] [Revised: 05/26/2006] [Accepted: 06/04/2006] [Indexed: 11/22/2022]
Abstract
GC-MS is a powerful tool for analysis of volatile oil, and resolutions of analytes were exclusively used as marker for optimization of the conditions. However, volatile oil usually contains heat labile components which may degrade and result in wrong results during GC analysis. In present study, based on both resolutions and stabilities of 11 sesquiterpenoids, GC-MS conditions were optimized for simultaneously quantitative determination of nine compounds including beta-elemene, curzerene, curcumol, isocurcumenol, germacrone, curdione, curcumenol, neocurdione and curcumenone in Ezhu. However, the other two compounds, i.e. furanodienone and furanodiene, were still thermal sensitive and not available for GC analysis. The results showed that both resolutions and stabilities of analytes should be considered for optimization of GC conditions because the properties of most components in volatile oil are unknown. Under optimum conditions, a capillary column (30 m x 0.25 mm i.d.) coated with 0.25 microm film 5% phenyl methyl siloxane was used for separation. Pulsed splitless inlet with temperature of 190 degrees C was selected for sample injection (0.2 microl). The calibration curves of nine sesquiterpenoids showed good linearity (r2>0.9989) within test ranges. The optimized method showed good repeatability for quantification of these nine components in Ezhu with intra- and inter-day variations of less than 1.42% and 2.79%, respectively. The validated method was successfully applied to quantify 9 sesquiterpenoids in 18 samples of 3 species of Curcuma used as Ezhu.

Abstract
A high-performance liquid chromatography coupled with diode array detection (HPLC-DAD) and pressurized liquid extraction was developed for simultaneous quantitative determination of 11 characteristic compounds, including curcumenone, curcumenol, neocurdione, curdione, isocurcumenol, furanodienone, curcumol, germacrone, curzerene, furanodiene and beta-elemene, in rhizomes of three species of Curcuma. The analysis was performed on an ODS C18 column. The mobile phase consisted of (A) water and (B) acetonitrile using a gradient elution. The peaks were monitored at both 214 nm and 256 nm. All calibration curves showed good linearity (r2 > 0.9996) within test ranges. This method showed good repeatability for the quantification of these eleven components in three species Curcuma rhizomes with intra- and inter-day variations of less than 1.57% and 1.98%, respectively. The validated method was successfully applied to quantify 11 investigated components in eighteen samples of three species of Curcuma, which is helpful to control their quality.

Abstract
A procedure that allows the identification and quantitative determination of eudesmane-type acids in the acidic part of the essential oil of Dittrichia viscosa sp. viscosa is described. The method involves the computer-aided analysis of the 13C-NMR spectrum of the mixture without the requirement of previous separation or derivatisation. The quantitative procedure was verified with costic acid standard and applied to three other acids which possess the same eudesmane framework.

Abstract
A commercial sample of the essential oil of Chenopodium ambrosioides L. from Madagascar was analysed by GC, GC-MS and 13C-NMR. By GC analysis, the major constituents were found to be ascaridole (1) (41.8%), isoascaridole (2) (18.1%), p-cymene (16.2%), alpha-terpinene (9.7%) and limonene (3.8%). However, ascaridole undergoes a partial thermal isomerisation to 2 and hence the amount of 1 is under-estimated by GC analysis. The actual contents of 1 and 2 (55.3 and 4.6%, respectively) were obtained following combined analysis of the sample by GC and 13C-NMR. Several hydroxy- and polyhydroxy-menthanes were identified by 13C-NMR.
