Phytochemical investigation of the MeOH extract of Dioscorea villosa rhizomes resulted in the isolation of two new bidesmosidic cholestane steroid glycosides, dioscoreavillosides A and B (1 and 2). In addition, the extract yielded 12 previously known furostan and spirostan steroid glycosides (3-14), along with diosgenin (15). Compounds 3-7, 9, 14, and 15 were isolated for the first time from D. villosa. The structures of the isolated compounds were determined using spectroscopic and chemical… CONTINUE READING
