| 摘要 | Two new C-22 steroidal lactone glycosides, named dracaenoside A and B were isolated from the methanol extract of the fresh stem of Dracaena cochinchinensis. Their structures were established as (20S)3beta,14alpha,16beta-trihydroxy pregn-5-ene-22-carboxylic acid (22,16)-lactone 3-O-alpha-L-rhamnopyranosyl (1-->2)[ alpha-L-rhamnopyranosyl (1-->4)]-beta-D-glucopyranoside and (20S)3beta, 14alpha, 16beta-trihydroxy pregn-5-ene-22-carboxylic acid (22,16)-lactone 3-O-alpha-L-rhanmopyranosyl (1-->2) [beta-D-glucopyranosyl(1-->3)]-beta-D-glucopyranoside by means of 2D NMR spectral and chemical methods. It is the first time that steroidal lactone glycosides were isolated from the genus Dracaena. |
