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3个乌素烷型三萜化合物:I、II、III。经光谱及化学方法鉴定，I为一新三萜化合物:[3-oxo—22α-hydroxy-ursan-12-en-30-oic acid(30，22α)-lactone]，命名为山海棠内酯(hypoglaulide)。II为雷公藤三萜酸C(triptotriterpenic acid C)，III为黑蔓酮酯甲(regelin)。这3个化合物都是首次从昆明山海棠中得到。

Abstract:A new ursane type triterpene compound, 3-oxo-22a-hydroxy- ursan-12-en-30-oic acid (30, 22a)-lactone named hypoglaulide (1), and two known compounds, triptotriterpenic acid C (H) and regelin (in), were isloated from the ethyl acetate soluble frac-tion of the alcohol extract of the root of Tripterygium hypoglaucum (Levl.) Levl. ex Hutch, by the means of column chromatography. Their structures were established on the basis of spec-tral and chemical methods.
