| Abstract: | The main saponin from the fresh tuber of Dioscorea composita was dioscin and from the fermented material 3-O-α-l-rhamnopyranosyl(1→4)-β-d-glucopyranosyl]diosgenin. The 13C NMR chemical shifts of saponins were used in the determination of their structure. No free sapogenin was isolated from the fresh tuber. |
