Abstract
Different parts of Uvaria ovata (Dunals) A, U. anonoides Baker f. and U. tortilis A. Chev were collected from Ivory Coast, in Toumodi (center), Agboville (south-east) and Sikensi (south), respectively. The essential oils, obtained by hydrodistillation using a Clevenger-type apparatus, were investigated by CG and CG/MS. The proportion of the chromatographed constituents identified varied from 92.5% to 98.5%. For U. ovata, the root bark oil comprised mainly camphene (10.2%), beta-pinene (10.1%), epi-alpha-cadinol (13.2%) and intermedeol (9.7%), while the oil of the stem bark was dominated by epi-alpha-cadinol (27.3%), intermedeol (11.9%) and benzyl benzoate (13.4%). The oil of the leaves showed beta-caryophyllene (15.6%), germacrene D (24.2%) and benzyl benzoate (18.3%) as the most abundant constituents. The leaf oil of U. anonoides was rich in 2,5-dimethoxy-p-cymene (15.5%), bicyclogermacrene (21.3%) and benzyl benzoate (8.7%), while, gamma-terpinene (31.7%), beta-caryophyllene (23.9%) and germacrene D (15.8%) constituted the main components of the stem bark oil of U. tortilis.
