摘要
从二杈狗牙花（Ｅｒｖａｔａｍｉａｄｉｖａｒｉｃａｔａ（Ｌ．）Ｂｕｒｋ）中共分离出８个已知化合物，分别为３个环菠萝蜜烷型三萜：ｃｙｃｌｏａｒｔ－２３－ｅｎｅ－３β，２５－ｄｉｏｌ（１），３β－ｈｙｄｒｏｘｙｃｙｃｌｏａｒｔ－２５－ｅｎｅ－２４－ｏｎｅ（２），ｃｙｃｌｏｅｕｃａｌｅｎｏｌ（３）；２个吲哚生物碱ｅｒｖａｔａｍｉｎｅ（４）和ｔａｂｅｒｎａｅｍｏｎｔａｎｉｎｅ（５）；其他是β－谷甾醇，３β－乙酰－香树脂醇和胡萝卜甙。它们均由波谱方法鉴定。
Eight compounds have been isolated from the aerial part of Ervatamia divaracata (L.)Burk. Their chemical structures have been identified as cycloart-23-ene-3β,25-diol(1), 3β-hydroxycycloart-25-ene-24-one(2)and cycloeucalenol(3),β-sitosterol, 3β-amyrin acetate, daucosterol, ervatamine(4), taberneamontanine(5)on the basis of spectral evidence. Three cycloartanes, cycloart-23-ene-3,25-diol(1), 3-hydroxycycloart-25-ene-24-one(2)and cycloeucalenol(3), are reported for the first time from the genus Ervatamia .
