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