山里红叶化学成分研究

目的:研究山里红(Crataegus pinnatifidaBge.var.majorN.E.B r.)叶中的化学成分。方法:用硅胶柱色谱、大孔树脂柱色谱和Sephadex LH-20柱色谱等技术进行分离纯化,根据理化性质和光谱数据进行结构鉴定。结果:得到14个化合物,分别为槲皮素Quercetin(1),金丝桃苷Hyperoside(2),槲皮素3-O-β-D-葡萄糖苷Quercetin 3-O-β-D-glucoside(3),芦丁Rutin(4),槲皮素3-O-α-L-鼠李糖(1-4)-α-L-鼠李糖(1-6)-β-葡萄糖苷]Quercetin 3-O--αL-rhamnopyransoyl(1-4)--αL-rhamnopyranosyl-(1-6)--βglucopyranoside](5),牡荆素V itexin(6),6″-O-乙酰基-牡荆素6-″O-acetyl-vitexin(7),牡荆素2-″O-鼠李糖苷V itexin 2-″O-rhamnoside(8),牡荆素4″-O-葡萄糖苷V itexin4-″O-glucoside(9),绿原酸Chlorogen ic ac id(10),熊果酸Ursolic ac id(11),β-谷甾醇-βS itosterol(12),β-胡萝卜苷β-Dau-costerol(13),正三十烷醇n-Triacontanol(14)。结论:5和14为首次从该属植物中分得。

Study on the Chemical Constituents of the Leaves from Crataegus pinnatifida Bge. var. major N. E. Br.

OBJECTIVE: to study the chemical components of the leaves from Crataegus pinnatifida Bge. var major N. E. Br. METHODS: Constituents were isolated by using silica gel, porous resin, Sephadex LH-20 chromatographic technique, etc. Their structures were elucidated by chemical and spectroscopic methods. RESULTS: Fourteen compounds were identified as quercetin (1), hyperoside (2), quercetin 3-O-beta-D-glucoside (3), rutin (4), quercetin 3-O-alpha-L-rhamnopyranosyl(1-4)-alpha-L-rhamnopyranosyl-(1-6)-beta-glucopyranoside] (5), vitexin (6), 6"-O-acetyl-vitexin (7), vitexin 2"-O-rhamnoside (8), vitexin 4"-O-glucoside (9), chlorogenic acid (10), ursolic acid (11), beta-sitosterol (12), beta-daucosterol (13), n-triacontanol (14). CONCLUSION: Compound 5 and 14 were isolated from Crataegus L. for the first time.
