Abstract

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 13 C-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).
