A New Ursene Type Triterpenoid from Crepis napifera

Laboratory of Phytochemistry, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650204

Received Date: 24 January 2000

A new triterpenoid, urs-20-en-3β-acetoxy-22α-ol, and three known compounds 3β-acetoxy-amyrin, 3β-acetoxy-lupeol, lupeol were isolated from the leaves of Crepis napifera (Franch.) Babc. Their structures were determined by means of spectroscopic studies.
