摘要Six new polyhydroxylated steroidal saponins, tupistrosides A-F (1-6), together with nine known steroids, were isolated from the fresh rhizomes of Tupistra yunnanensis. Their structures were elucidated to be (25S)-1 beta,4 beta,5 beta-trihydroxy-spirostane-3 beta-yl-O-alpha-L-arabinopyranoside (1), 1 beta,24 beta-dihydroxy-spirost-5,25(27)-dien-3 alpha-yl-O-beta-D-glucopyranoside (2), (22S,25S)- 1 alpha,2 beta,3 alpha,5 alpha-tetrahydroxy-furo-spirostane-26-yl-O-beta-D-glucopyranoside (3), 1 beta,3 alpha,22 xi-trihydroxy-furost-5,25(27)-dien-26-yl O-beta-D-glucopyranoside (4), 26-O-beta-D-glucopyranosyl-1 beta,22-dihydroxy-furost-5-en-3 alpha-yl O-beta-D-glucopyranoside (5) and 22-methoxy-1 beta,2 beta,3 beta,4 beta,5 beta,7 alpha-hexahydroxy-furost-25(27)-en-6-one-26-yl O-beta-D-glucopyranoside (6), respectively, by means of spectroscopic analysis and the results of acid hydrolysis.
