The compositions of essential oil obtained from leaves, flowers and fruits of Lantana camara L. growing in wild at Côte d'Ivoire, were investigated by GC and 13C NMR. Thirty-seven compounds accounting for 88.3-94.5% of the oils have been identified. The leaf, flower and fruits of L. camara produced sesquiterpene-rich essential oils predominated by ( E)-β-caryophyllene and α-humulene, in addition to the important content of sabinene, β-phellandrene and thymol as monoterpenes. It was found the new chemical profiles of L. camara.

The essential oils isolated from aerial parts of Cassytha filiformis L. harvested in five locations of Côte d'Ivoire were analyzed by GC(RI), GC-MS and 13C-NMR. The oils were dominated by sesquiterpene derivatives and the content of the main components varied substantially from sample to sample: (E)-β-caryophyllene (1.5-34.9%), bicyclogermacrene (1.0-25.8%), α-humulene (0.5-22.0%), spathulenol (1.0-18.5%) and germacrene D (6.6-16.6%). Two compositions could be distinguished: (i) bicyclogermacrene, germacrene D, spathulenol (2/5 samples) and (ii), (E)-β-caryophyllene, α-humulene (3/5 samples).

The combination of 13C nuclear magnetic resonance (NMR) spectroscopy, gas chromatography (GC) (retention index), and gas chromatography-mass spectrometry was used to determine the chemical composition of essential oils of Piper guineense and Piper umbellatum from Côte d’Ivoire. Thus, 54 components, accounting for 91.5% to 97.6%, were identified in the essential oil from aerial parts of P. guineense. In P. umbellatum leaf oil, 49 compounds accounting for 92.8% to 98.7% were identified. Both plants oils were dominated by monoterpenes and sesquiterpenes, with α-phellandrene, (2 E,6 E)-farnesol, and linalool as major compounds of P. guineense, whereas the most abundant components of P. umbellatum were linalool and ( E)-β-caryophyllene. (2 E,6 E)-Farnesol, identified for the first time in the essential oil from aerial parts of P. guineense, induced a new chemical composition.

Chemical Variability

Chemical variability of a plant from various continents or collected in different localities is well known and justifies its different biological activities. Thus, the present study was undertaken to evaluate the chemical variability of essential oils from leaves of Tridax procumbens Linn from five localities of Cote d'Ivoire. Essential oils have been extracted by hydrodistillation with yields varying from 0.077 to 0.079% depending on the locality. Gas chromatography and mass spectrometry analysis of essential oils showed a predominance of thymol (20.9 to 68.9%) in the oils from all the localities except that from Yamoussoukro which is of an α-acoradiene (28.9%) predominance. Several of the most important and variously distributed minor compounds consist of p-cymene (2.2 to 11.3%), β-caryophyllene (1.5 to 6.0%), β-selinene (1.8 to 10.0%), α-selinene (0 to 7.3%), elemol (0 to 16.0%), α-eudesmol (0 to 7.5%), 6,10,14-Trimethylpentadecan-2-one (0.9 to 7.2%) and phytol (0 to 7.2%). The comparative study of the chemical compositions of essential oils showed that thymol is a marker of the plant. Tridax procumbens acclimated in Côte d’Ivoire have been grouped into three chemotypes of thymol and other compounds.Keywords: Essential oils, Tridax procumbens, Chemical variability, Thymol, Chemical composition
