【摘要】 从云南产羯布罗香(Dipterocarpus tubinatus Gaertn. f.)树脂中分离得到6个三萜化合物,鉴定为羟基达玛烯酮—Ⅱ(hydroxydammarenone-Ⅱ,达玛烯二醇—Ⅱ(dammarenediol—Ⅱ),白桦脂酸(betulonk acid),亚细亚酸(asiatic acid),3,23-O-异丙叉亚细亚酸(3,23-O-isopropylidene asiatic acid)和崩大碗酸(madasiatic acid)。其中崩大碗酸系首次从龙脑香科树脂中分离得到。更多还原

【Abstract】 The resin of Dipterocarpus lubinatus Gaertn. f. native to the south of Yunnan(China) have been investigated. From which, six triterpenes-hydroxydammarenone-Ⅱ(1), dammarenediol-Ⅱ (2), betulonic acid(3), asiatic acid(4), 3,23-o-isopropylidene asiatic acid(5) and madasiatic acid (6) were isolated and established by means of spectral methods. Madasiatic acid was first isolated from the resin in Dipterocarpaceae.更多还原
