[Studies on the sapogenins and prosapogenins in Ardisia pusilla A. DC].
Two new saponins were isolated from Ardisia pusilla and proved to have marked immunological function and antitumor activity. Acidic hydrolysis of saponin I gave five sapogenins and two prosapogenins. The structures of three sapogenins were elucidated as cyclamiretin A, C, D and two prosapogenins as cyclamiretin D-3-O-alpha-L-arabipyranoside and cyclamiretin D-3-O-beta-D-glucopyranosyl-(1-->2)-alpha-L-arabipyranoside.
