摘 要 ：从金樱子的乙醇提取物及石油醚乳化层的乙酰化物中分别得到6个化合物,经理化常数和光谱分析,分别鉴定为2α,3β,19α,23-四羟基乌苏-12-烯-28-羧酸,2α,3α,19α,23-四羟基乌苏-12-烯-28-羧酸,euscaphic acid,β-谷甾醇,胡萝卜素,2α,3β-二羟基羽扇豆-28-羧甲酯的二乙酰化物。

Abstract:Six compounds were isolated from Rosa laevigata. Five of them were obtained from the ethanolic extract and identified as 2α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid, 2α,3α,19α,23-tetrahydroxyurs-12-en-28-oie acid, euscaphic acid, β-sitosterol and daucosterol. The other one was obtained from the acetate of emulsive layer of the petroleum ether and elucidated as 2α,3β-dihydrolup-28-methyl ester diacetate.
