ABSTRACT
This study made it possible to characterise by GC (in combination with retention indices), GC-MS and 13C NMR, the chemical composition of the essential oils from Solanum rugosum and Solanum erianthum, two Solanaceae of the Ivorian flora. The two essential oils were characterised by a very high proportion of sesquiterpenes. Specifically, the essential oil of S. rugosum was dominated by (E)-ß-caryophyllene (33.7%), ß-elemol (19.8%) and germacrene D (14.4%), while that of S. erianthum was mainly composed of α-humulene (38.6%), ß-elemol (17.8%) and (E)-ß-caryophyllene (16.7%). The chemical composition of Solanum rugosum is described here for the first time.

The n-butanol extract of the roots of Glyphaea brevis was analysed. HPLC analysis suggested the presence of phenolic compounds like protocatechuic acid (PCA). The extract showed moderate cytotoxic activity against C6 glioma cells (EC50 > 1 mg/ml).
