摘要:
目的:对中药戟叶酸模正丁醇萃取物的化学成分进行研究。方法:利用正相和反相硅胶柱、羟丙基葡萄糖凝胶柱色谱等方法对化学成分进行分离及纯化,根据化合物理化性质及波谱数据鉴定其结构。结果:分离得到10个化合物,分别为nepodin-8-O-β-d-glucopyranoside(1),6-hydroxymusizin-8-O-β-d-glucopyranoside(2),torachysone-8-O-β-d-glucopyranoside(3),isorhamnetin(4),emodin-8-O-β-d-glucopyranoside(5),7-hydroxy-5-methyl-coumarin-4-O-β-d-glucopyranoside(6),nepodin-8-O-β-d-(6'-O-acetyl)-glucopyranoside(7),2-(2',6'-dihydroxybenzoyl)-5-methylbenzoic acid-3-O-β-d-glucopyranoside(8),polydatin(9)和rumexoside(10)。结论:化合物6,7,8为首次从酸模属植物中分离得到,化合物1,2,3,4,5,9,10为首次从该植物中分离得到。
