Abstract

Gliricidia sepium (Jacq.) Steud. leaves were extracted separately with methanol, diethyl ether, hexane, and ethyl acetate. The methanol extract caused a significantly high mortality rate in the bnne shrimp bioassay. It further showed a marked inhibition of fungal growth in the anti-mycotic bioassay. Thin layer chromatography identified anthraquinone, in particular anthrone, tannins, and coumarin as the major constituents in the methanol extract. These substances can be the bases for the observed biological activities and can possibly account for the purported therapeutic effects of the plant.
