摘要
目的研究鄂西大蓟Cirsium henryi茎叶的化学成分。方法使用多种柱色谱技术对鄂西大蓟茎叶95%乙醇提取物的石油醚、醋酸乙酯和正丁醇部位进行分离纯化,根据波谱数据和理化性质确定各化合物的结构。结果从鄂西大蓟茎叶石油醚部位分离得到7个化合物,分别鉴定为硬脂酸(1)、二羟丙基软脂酸酯(2)、软脂酸(3)、蒲公英甾醇(4)、伪蒲公英甾醇(5)、蒲公英甾醇乙酸酯(6)、β-谷甾醇(7);从醋酸乙酯部位分离得到6个化合物,分别鉴定为胡萝卜苷(8)、原儿茶酸(9)、蒙花苷(11)、芹菜素(12)、槲皮苷(13)、金合欢素(14);从正丁醇部位分离得到3个化合物,分别鉴定为尿嘧啶(10)、金合欢素-7-O-β-D-葡萄糖苷(15)、4-羟基-3,5-二甲氧基苯甲酸(16)。结论化合物3、10~16为首次从该植物中分离得到,化合物10、13、16为首次从蓟属植物中分离得到。
Objective To study the chemical constituents from the stems and leaves of Cirsium henryi. Methods The chemical constituents were isolated by various chromatography techniques and their structures were elucidated on the basis of spectroscopic analysis. Results Sixteen compounds were isolated and identified to be stearic acid(1), 2,3-dihydroxypropyl hexadecanoate(2), palmitic acid(3), taraxasterol(4), pseudo taraxasterol(5), taraxa-sterol acetate(6), β-sitosterol(7), daucosterol(8), protocatechuic acid(9), uracil(10), linarin(11), apigenin(12), quercitrin(13), acacetin(14), acacetin-7-O-β-D-glucoside(15), and 4-hydroxy-3,5-dimethoxy benzoic acid(16), respectively. Conclusion Compounds 3 and 10—16 are isolated from the plant for the first time, and compounds 10, 13, and 16 are isolated from the plants of Cirsium Mill. Emend. Scop. for the first time.
