目的 对刺五加Acanthopanax senticosus的化学成分进行研究。方法 刺五加药材用75%乙醇提取,依次用石油醚、醋酸乙酯萃取,对醋酸乙酯部分采用硅胶柱色谱、反相制备色谱等技术进行分离,根据波谱学数据(MS、1H-NMR、13C-NMR)进行化合物的结构鉴定。结果 从醋酸乙酯部分分离得到19个化合物,分别鉴定为槲皮素(1)、槲皮苷(2)、山柰酚(3)、金丝桃苷(4)、芦丁(5)、金合欢素(6)、大豆苷(7)、3′-甲氧基大豆苷(8)、葛根素(9)、3′-甲氧基葛根素(10)、4′-甲氧基葛根素(11)、丁香醛(12)、丁香酸(13)、紫丁香酸葡萄糖苷(14)、异嗪皮啶(15)、2, 3-二 (3′, 4′-二甲氧基苄基)-2-丁烯-4-内酯(16)、l-芝麻酯素(17)、methylpluviatolide(18)、4′-羟基-2′-甲氧基肉桂醛(19)。结论 化合物6~11、14、16、18、19为首次从该属植物中分离得到。

Objective To study the chemical constituents of Acanthopanax senticosus. Methods A. senticosus was extracted with 75% EtOH and separated with petroleum ether and EtOAc, successively. The EtOAc-soluble fraction was isolated by column chromatography and RP-preparative HPLC. Their structures were identified by spectroscopic method (MS, 1H-NMR, and 13C-NMR). Results Nineteen compounds were isolated from the EtOAc fraction of A. senticosus and identified as quercetin (1), quercitrin (2), kaempferol (3), hyperoside (4), rutin (5), acacetin (6), daidzin (7), 3′-methoxydaidzin (8), puerarin (9), 3′-methoxypuerarin (10), 4′-methoxypuerarin (11), syringaldehyde (12), syringic acid (13), glucosyringic acid (14), isofraxidin (15), 2, 3-di(3′, 4′-methyl-endioxy-benzyl)-2-buten-4-olide (16), l-sesamin (17), methylpluviatolide (18), and 4′-hydroxy-2′-methoxycinnamaldehyde (19). Conclusion Compounds 6—11, 14, 16, 18, and 19 are isolated from the plants in Acanthopanax (Deche et Planch.) Miq. for the first time.
