摘要(Abstract)：
目的对岗梅叶的化学成分进行研究。方法采用反复硅胶柱色谱、凝胶柱色谱进行分离?纯化,并通过其理化性质,结合光谱数据鉴定其化学结构。结果分离得到9个化合物,分别鉴定为:rotundioic acid(1)、2α,3β,19α-三羟基乌索-12-烯-23,28-二羧酸(2)、2α,3β,19α-三羟基齐墩果-12-烯-23,28-二羧酸(3)、山柰酚(4)、山柰酚-3-O-β-D-葡萄糖苷(5)、2(E)-2,6-二甲基-2,7-辛二烯-6-羟基-1-醇苷(6)、2,3-二羟基苯甲酸(7)、β-谷甾醇(8)、胡萝卜苷(9)。结论化合物1-7为从该种植物中首次分离得到。
Objective To study the chemical constituents of the leaves of Ilex asprella in order to reveal the active components for their further development.Methods The compounds were isolated by chromatography on silica gel columns and identified on the basis of physico-chemical properties and spectral analysis.Results Nine compounds were obtained and identified as rotundioic acid(1),2α,3β,19α-trihydroxy-urs-12-ene-23,28-dioic acid(2),2α,3β,19α-trihydroxyolean-12-ene-23,28-dioic acid(3),kaempferol(4),kaempferol-3-O-β-D-glucoside(5),colorless oil(6),balanophonin(7),β-sitosterol(8),daucosterol(9).Conclusions Compounds 17 are isolated from this plant for the first time.
