摘要: 从二杈狗牙花(Ervatamia divaticata (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(l),3β-hydroxycycloart-25-ene-24-one(2),cycloeucaleno(3);2个吲哚生物碱ervatamine(4)和tabernaemontanine(5);其他是β一谷甾醇,3β-乙酞-香树脂醇和胡萝卜甙。它们均由波谱方法鉴定。其中环菠萝蜜烷型三萜系首次被发现存在于狗牙花属植物中。

Abstract: Eight compounds have been isolated from the aerial part of Ervatamia dwaracata (L.) Burk. Their chemical structures have been identified as cycloart - 23 - ene - 3β, 25 - diol (1), 3β - hydroxycy-cloart-25-ene-24-one (2) and cycloeucalenol (3), β - sitosterol, 3β - amyrin acetate, daucos-terol, ervatamine (4), tabemeamontanine (5) on the basis of spectral evidence. Three cycloartanes, cy-cloart - 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.

Key words: Ervatamia divaracata
