Abstract
A new bisdesmosidic cholestane glycoside, designated as concinnasteosi de A, was isolated from the fresh stems of Dracaena concinna. The stru cture was determined to be 1 beta,3 beta,16 beta-trihydroxy-5 alpha-ch olesta-7,23-dione 1-O-alpha-L-rhamnopyranosyl 16-O-beta-D-glucopyranos ide on the basis of spectroscopic analysis, including 2D NMR technique s. Concinnasteoside A is believed to be the first example of a cholest ane glycoside from a plant of the genus Dracaena.
