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 composition of rambling leaves. Methods The compounds were isolated and purified by silica gel column chromatography and column chromatography. Their chemical structures were identified by their physicochemical properties and spectral data. As a result, nine compounds were isolated and identified as: rotundiioic acid (1), 2α, 3β, 19α-trihydroxy urethane-12-ene-23,28-dicarboxylic acid (2), 2α, 3β, 19α-tris Hydroxyolean-12-ene-23,28-dicarboxylic acid (3), kaempferol (4), kaempferol-3-O-β-D-glucoside (5), 2(E)- 2,6-Dimethyl-2,7-octadiene-6-hydroxy-1-alcoholic acid (6), 2,3-dihydroxybenzoic acid (7), β-sitosterol (8), and carotenoids (9). Conclusion Compounds 1-7 were isolated from this plant for the first time.
