Physical characteristics and Chemical compositions of Leaves extracts of Sorindeia grandifolia Engl. (Anacardiaceae) harvested at Kato, Benin

Abstract

The results brought back at the end of this work concern various chemical constituents of S. grandifolia leaves collected in Benin. The major compounds ( 4%) of essential oils obtained after hydrodistillation and analysis by coupling gas chromatography with spectrometry mass are constituted of : limonene (20.2%), (E)--ocimene (7.6-17.8%), (Z)--ocimene (11.4%), -cadinene (7.0%), selin-11-en-4--ol (4.5-5.7% ), palmitic acid (4.3-6.2%), -pinene (5.5%), α-selinene (5.5%), -phellandrene (5.2%), β-selinene (4.9%), β-elemene (4.5%).The lipidic fractions realized from petroleum ether extracts are marked by importants rates of arachidic acid (22.5%), palmitic acid (20.3%) and of linoleic acid (15.9 %). The phytochemical analysis showed relatively a large content of coumarins, gallic tannins, flavones, leucoanthocyans and saponins in opposition to the other secondary metabolites.
