摘要：

A new triterpene 3-O-[a-L-Rhamnopyranosyl (1-->2)-beta-D-xylopyranosyl(1-->2)-beta-D-xylopyranosyl]-16 beta,23 (R): 16 alpha,30 alpha-diepoxy-20(S)-hydroxydammar-24-ene (1) was isolated from the roots of Centrosema bracteosum. The structure of this triterpenoid glycoside was elucidated by spectroscopic analysis of the natural product (1) and its peracetyl derivative (1a), including 2D NMR experiments.
