Estimation of Tannin, Saponin, Oxalate, Cyanogenic and Cardiac Glycosides in Garsinia Kola

Abstract

The presence of some secondary plant metabolites — tannin, saponin, oxalate, cyanogenic and cardiac glycosides were done in Garsinia Cola. The tannin, saponin and oxalate content were 0.69 ± 0.01, 15.79 ± 0.28 and 1.707 ± 0.13mg/100g of dry sample respectively. The cyanogenic and cardiac glycosides were 59.56 ± 0.05 and 67.10 ± 0.03mg/100g dry matter respectively. The levels of oxalate, tannin and cyanogenic glycosides of the kola were observed to be very low while the levels of saponin and cardiac glycoside were observed to be very high when compared to some internationally accepted standards.
