 note = {Five triterpenoids were isolated from a chloroform-soluble fraction in a methanol extract of the leaves of Cynanchum liukiuense Werb, in addition to methyl stearate, phytosterols, and phytosterol glycosides. These triterpenoids were identified as 3β- acetyloxy-urs-12-ene (α-amyrin acetate), 3β-acetyloxy-olean-12-ene (β-amyrin acetate), (4β)-D-friedoolean-14-en-3β-ol (taraxerol), olean-12-en-3β-ol (β-amyrin), and lup-20(29)-en-β-ol(lupeol), respectively. The phytosterols consisted of stigmastanol, stigmasterol, and campesterol by co-GC and GC-MS analyses and the phytosterol glycosides mainly did of the glucosides of stigmastanol, β-sitosterol, stigmasterol, and campesterol., 紀要論文},
