dc.description.abstractTwo saponin steroids were isolated from the butanol extracts of the rhizomes of Dioscorea zingiberensls C. H. Wright collected in Quảng Ngãi, Vietnam and indentified as: Diosgenln-3-O-α-L-rhamnopyranosyl-(1→4)-[α-L-rhamnopyranosyl- (1→2)]-β-D-glucopyranosyl (2D1) and diosgefìin-3-O-fỉ-D-glucopyranosyl-(1→4)-α-L-rhamnopyranosyl-( 1→2)]-β-D- glucopyranosyl (2E1). Their chemincal structures were elucidated by physicochemical charactehzation and spectroscopic analysis (1D, 2D- NMR, MS) in reference to the literature. The occurence of these two saponin steroids in the plant Dioscorea zingiberensis C. H. Wright was reported for the first time.vi_VN
