摘要

Chemical investigation of the aerial parts of Bunge (Leguminosae) led to the isolation and identification of a new cycloartane triterpene glycoside - lehmanniaside (2'-O-acetyl-3--O-D-xylopyranosyl-3,6,16,24-tetrahydroxy-20,25-epoxycycloartane). Its structure was elucidated by means of spectroscopic analysis (HR-MS, 1D and 2D NMR). Bioassays showed that lehmanniaside exhibits weak anthelmintic, antifungal, and cytotoxic activities.
