Abstract
The chemical composition of 45 essential oil samples isolated from the leaves of Polyalthia oliveri harvested in three Ivoirian forests was investigated by GC-FID (retention indices measured on two columns of different polarities), and by (13) C-NMR, following a method developed in our laboratory. In total, 41 components were identified. The content of the main components varied drastically from sample to sample: (E)-β-caryophyllene (1.2 - 50.8%), α-humulene (0.6 - 47.7%), isoguaiene (0 - 27.9%), alloaromadendrene (0 - 24.7%), germacrene B (0 - 18.3%), δ-cadinene (0.4 - 19.3%), and β-selinene (0.2 - 18.5%). The analysis of six oil samples selected in function of their chromatographic profiles is reported in detail. The 45 oil compositions were submitted to hierarchical cluster and principal components analysis, which allowed the distinction of three groups within the oil samples. The compositions of the oils from group I (15 samples) and II (12 samples) were dominated by (E)-β-caryophyllene and α-humulene, respectively. Oil samples of group III (18 samples) needed to be partitioned into four subgroups III.1-III.4 whose compositions were dominated by alloaromadenrene, isoguaiene, germacrene B, and δ-cadinene, respectively.

Polyalthia longifolia produces sesquiterpene-rich essential oils (EOs) whose compositions varied substantially from sample to sample depending on the origin of the plant (Nigeria and Vietnam). Nothing is known about the phytochemistry of Ivoirian P. longifolia. The aim of the present study was to characterize Ivoirian P. longifolia through the chemical composition of the leaf oil and to develop a strategy that allows the identification of minor oxygenated sesquiterpenes whose MS data are not com...

Abstract The stem bark of Polyalthia oliveri was screened for its chemical constituents using liquid chromatography high resolution mass spectrometry resulting in the isolation of three indolosesquiterpene alkaloids named 8 α -polyveolinone ( 1 ), N -acetyl-8 α -polyveolinone ( 2 ) and N -acetyl-polyveoline ( 3 ), together with three known compounds, dehydro- O -methylisopiline ( 4 ), N -methylurabaine ( 5 ) and polycarpol ( 6 ). The structures of the compounds were elucidated by means of high r...

The chemical composition of 48 leaf oil samples isolated from individual plants of Cleistopholis patens (Benth.) Engl. et Diels harvested in four Ivoirian forests was investigated by GC-FID (determination of retention indices), GC/MS, and 13C-NMR analyses. The main components identified were β-pinene (traces–59.1%), sabinene (traces–54.2%), (E)-β-caryophyllene (0.3–39.3%), linalool (0.1–38.5%), (E)-β-ocimene (0.1–33.2%), germacrene D (0.0–33.1%), α-pinene (0.1–32.3%), and germacrene B (0–21.2%)....

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 13C-NMR spectrum of the ...

Abstract Aim of the study In a search for new plant-derived biologically active compounds against malaria parasites, we have carried out an ethnopharmacological study to evaluate the susceptibility of cultured Plasmodium falciparum to extracts and fractions from seven Cameroonian medicinal plants used in malaria treatment. We have also explored the inhibition of the Plasmodium falciparum cysteine protease Falcipain-2. Materials and methods Plant materials were extracted by maceration in organic ...

Introduction The study of taxanes is a hot topic worldwide because of their potential activity against cancer. Analysis of taxanes in extracts of various Taxus species is generally achieved using HPLC. Objective The aim of the current work was to identify taxanes in different fractions of extracts from Taxus baccata L. using the computer-aided analysis of their 13C-NMR spectra. Methodology A computerised procedure, based on 13C-NMR spectroscopy using literature data, has been developed in order ...

We report a methodology that allows identification and quantitative determination of individual acidic and neutral diterpenes in natural mixtures, using the computer-aided analysis of their 13C-NMR spectra. The analytical procedure was validated on artificial mixtures and then applied to authentic oleoresins of Pinus nigra. Up to eleven diterpenes, which represented 63% of the total composition of the oleoresin, were identified and quantified without previous separation or derivatization.

Abstract The leaf oils of the four Australian species of Polyalthia were examined. P. australis gave an oil in which the major components were p-caryophyllene (4–15%), germacrene D (1–13%), bicyclogermacrene (1–10%), caryophyllene oxide (6–10%) and spathulenol (7–24%). P. michaelii gave an oil with spathulenol (42.2%) as the principal compnent. P. nitidissima appeared to exist in two chemotypes: one in which α-pinene (10–12%), limonene (4–6%) and (E)-β-ocimene (0.7–2%) were present, though the m...

The polar part of commercial Haitian vetiver oil was converted to the methyl ethers, and this product separated by distillation and repeated flash chromatography (FC). The following new (nor-) sesquiterpene alcohols were isolated as their methyl ethers and identified by their 1H- and 13C-NMR spectra: 12-nor-ziza-6(13)-en-2β- (2) and -2α-ol (3), eudesma-4(15),7-dien-3β- (7) and -2β-ol (18), eudesma-3,5-dien-1α-ol (26), eremophila-1(10),4(15)-dien-2α-ol (31), eremophila-1(10),11-dien-2α-ol (nootka...

AbstractThe chemical composition of 35 leaf oil samples from Polyalthia longifolia (Sonnerat) Thwait., growing in five districts in Abidjan and its suburbs, has been investigated by GC(FID) in combination with retention indices, GC–MS and 13C-NMR. In total, 30 individual components have been identified, mostly sesquiterpenes. The contents of the main components varied substantially from sample to sample: (E)-β-caryophyllene (18.9–31.4%), α-zingiberene (6.1–22.1%), allo-aromadendrene (12.4–17.3%)...

The chemical composition of trunk bark oil from Cleistopholis patens Engler and Diels, growing wild in Cote d'Ivoire, has been investigated by GC(FID) in combination with retention indices, GC/MS and 13C-NMR. Moreover, one oil sample has been subjected to CC and all the fractions analyzed by GC(RI) and 13C-NMR. In total, 61 components have been identified, including various sesquiterpene esters scarcely found in essential oils. 13C-NMR was particularly efficient for the identification of a compo...
