摘要: 目的: 研究紫葳科角蒿属植物大花鸡肉参的化学成分。 方法: 利用硅胶色谱柱,制备薄层色谱和葡聚糖凝胶Sephadex LH-20柱纯化,硅胶柱色谱进行分离纯化,通过理化常数和光谱分析鉴定化合物的结构。 结果: 从大花鸡肉参的乙醇提取物中分离并鉴定了12个化合物的结构,分别是:邻-羟基苯甲酸(O-Hydroxybenzoic acid)、棕榈酸(Palmitic acid)、正二十六烷酸(Hexacosanoic acid)、β-谷甾醇(β-Sitosterol)、β-胡萝卜苷(Daucosterol)、齐墩果酸(Oleanolic acid)、乌苏酸(Ursolic acid)、槲皮素(Quercetin)、槲皮苷(Vincetoxicosi-de B)、对羟基苯甲酸(p-Hydroxy benzoic acid)、3-甲氧基-4-羟基苯甲酸(3-Methoxy 4-hydroxy-benzoic acid)、豆甾醇(Stigmasterol)。 结论: 化合物1-12均为首次从该植物中分离得到。Abstract: Objective: To study the chemical constituents of Incarvillea mairei var.granditlora(Wehrhahn) Grierson. Methods: Isolation and purification were carried out by macroporous absorption resin and silica gel column chromatography,and twelve compounds were identified by spectral and chemical methods. Results: Twelve compounds were obtained from alcohol extract and were determined as o-hydroxy benzoic acid,palmitic acid,hexacosanoic acid,β-sitosterol,daucosterol,oleanolic acid,ursolic acid,quercetin,vincetoxicoside B,p-hdroxy benzoic acid、3-mthoxy 4-hydroxy-benzoic acid,sgmasterol. Conclusion: All of 12 compounds were obtained from the plant for the first time.
