Tang Shi-rong and Wu Yie-feng   

Abstract: Two trisaecharides of diosgenin (A, B) had been isolated from the rhizome of Dioseorea gracillima Maq. (collected from Jiangsi, Lu Shan). By means of acetylafion, acid hydrolysis, IR, MS and 13C-NMR etc. saponin A and saponin B were identifieated as dioscin and gracillin, respectively. Its yieldingratio is 3:1 (A:B).
