摘要：
Three new pregnane oligoglycosides, medidesmine, hemisine and desmisine isolated from the plant Hemidesmus indicus were identified as sarcostin-3-O-alpha-D-glucopyranosyl (1 --> 4)-O-beta-D-digitoxopyranosyl (1 --> 4)-O-beta-D-oleandropyranoside, calogenin-3-O-beta-D-cymaropyranosyl (I --> 4)-O[3-O-methyl]beta-D-glucopyranosyl (1 --> 4)-O-beta-D-glucopyranosyl (1 --> 4)-O-beta-D-cymaropyranoside and calogenin-3-O-beta-D-xylopyranosyl (1 --> 4)-O-beta-D-digitoxopyranosyl (1 --> 4)-O-beta-D-xylopyranosyl (1 --> 4)-O-beta-D-digitoxopyranoside, respectively, with the help of FAB-MS, EI-MS, H-1 and C-13 NMR spectroscopy. along with chemical transformations.
