摘 要 ：从昆明山海棠(Tripterygium hypoglaucum)根的乙醇提取物乙酸乙酯可溶部分中分离得到7个齐墩果烷型三萜化合物，经光谱分析确定了它们的化学结构：I为一新化合物(3β-hydroxy-olean-5,12-dien-28-oic acid)，命合为山海棠萜酸(hypoglauterpenic acid)；II为雷公藤三萜酸A(triptotriterpenic acid A);Ⅲ为雷公藤内酯乙(wilforlide B)；IV为雷公藤内酯甲(wilforlide A)；V为齐墩果酸乙酸酯(oleanolic acid acetate)；VI为齐墩果酸(oleanolic acid)；亚为 3-epikatonic acid.

Abstract:One new oleanane type triterpene compound ( 3β-hydroxy-olean-5, 12-dien-28-oic acid) , named hypoglauterpenic acid ( I ) , and six known oleanane type triterpene compounds, triptotriterpenic acid A (H), wilforlide B (ffl), wilforlide A (IV), oleanolic acid acetate (V), oleanolic acid (VI) and 3-epikatonic acid, were isolated from the ethyl acetate soluble fraction of the alcohol extract of the root of Tripterygium hypoglaucum (Levl. ) Levl. ex Hutch by the means of column chromatography.
