Abstract:
From the rhizomes of T. Communis two steroidal glycosides were isolated and identified as dioscin [diosgenin bis-alpha-L-rhamnopyranosyl (1----2 and 1----4) -beta-D-glucopyranoside] and gracillin [diosgenin-alpha-L-rhamnopyranosyl (1----2)-beta-D-glucopyranosyl (1----3)-beta-D-glucopyranoside] by 1H and 13C NMR spectroscopy, MS (FAB) and chemical evidences. It is interesting to note that this is the first report of the occurrence of dioscin and gracillin in the rhizomes of T. communis.
