摘要: [摘要]目的:研究野生云南山楂果实中的化学成分及其降脂活性。方法:运用硅胶、Sephadex LH-20等柱色谱对化合物进
行分离纯化,并通过理化性质及现代波谱分析等手段对化合物进行结构鉴定;采用高脂HepG2细胞模型进行体外降脂活性
测试。结果:从野生云南山楂果实95%乙醇提取物中分离鉴定了6个单体化合物,分别为苯甲酸(1)、2-羟基丁二酸二甲酯
(2)、2-羟基丁二酸-1-甲基酯(3)、β-谷甾醇(4)、胡萝卜苷(5)、槲皮素(6);化合物2~5在200 μmol/L浓度下均未显示出明
显的降脂率。结论:化合物2和3为首次从山楂属植物中分离得到,化合物1为首次从该植物中分离得到,所有供试化合物
均无体外降脂活性。

Abstract: 〔Abstract〕Objective: To study the chemical constituents of Crataegus scabrifolia(Franch.)Rehd. and their lipid-lowering activities.
Methods: The compounds were isolated and purified by column chromatography padded with silica gel and Sephadex LH-20, and their
structures were identified based on the comprehensive analyses of the physicochemical properties and spectral data. The lipid-lowering
activity in vitro was evaluated by cellular model of high-fat HepG2. Results: Six compounds were obtained from the 95% ethanol extract
of the fruits of wild C. scabrifolia and identified as benzoic acid(1), 2-hydroxybutanedioic acid dimethyl ester(2), 2-hydroxy-succinic
acid 1-methyl ester(3), β-sitosterol(4), daucosterol(5), and quercetin(6). Compounds 2-5 showed no significant lipid reduction at
200 μmol/L concentration. Conclusion: This was the first report on compounds 2 and 3 from the plants of Genus Crataegus, and
compound 1 was isolated from C. scabrifolia for the first time. Compounds 2-5 had no lipid-lowering activity in vitro.
