Deskripsi
ABSTRACT A new triterpene 3-O-[α-L-Rhamnopyranosyl (1 ->2)-(β-D-xy-lopyranosyl 16β,23 (R): 16α,30α-diepoxy-20(S)-hydraxydammar-24-ene (1) was isolated from 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.
