摘要：

A new bisdesmosidic cholestane glycoside, designated as concinnasteoside A, was isolated from the fresh stems of Dracaena concinna. The structure was determined to be 1 beta,3 beta,16 beta-trihydroxy-5 alpha-cholesta-7,23-dione 1-O-alpha-L-rhamnopyranosyl 16-O-beta-D-glucopyranoside on the basis of spectroscopic analysis, including 2D NMR techniques. Concinnasteoside A is believed to be the first example of a cholestane glycoside from a plant of the genus Dracaena.
