Study on chemical constituents from cyclohexane soluble part of Psoraleae Fructus

目的研究补骨脂Psoraleae Fructus 70%乙醇水提取物的环己烷溶性部分的化学成分。方法采用硅胶、高效液相色谱等柱色谱方法进行分离纯化,通过化合物的谱学数据鉴定其结构。结果从补骨脂70%乙醇水提取物的环己烷溶性部分分离出21个化合物,分别鉴定为补骨脂醚(1)、对羟基苯甲醛(2)、邻苯二甲酸二异辛酯(3)、补骨脂醚酚G(4)、补骨脂醚酚H(5)、双补骨脂酚V(6)、双补骨脂酚I(7)、双补骨脂酚H(8)、双补骨脂酚F(9)、双补骨脂酚D(10)、双补骨脂酚G(11)、豆甾醇(12)、补骨脂查耳酮(13)、补骨脂定(14)、补骨脂二氢黄酮甲醚(15)、异补骨脂素(16)、补骨脂素(17)、豆甾醇-3-O-β-D-吡喃葡萄糖苷-6′-O-棕榈酸酯(18)、4-羟基合生果素(19)、新补骨脂宁(20)和6-异戊烯基柚皮素(21)。结论化合物1、4、5和6为4个新的化合物。

Objective To study chemical constituents of cyclohexane soluble part in 70%ethanol aqueous extract of Psoraleae Fructus(the fruits of Psoralea corylifolia).Methods The compounds were separated and purified by silica gel and high performance liquid column chromatographies,and their structures were determined by spectroscopic data analyses.Results Twenty-one compounds were obtained and identified as psoracorylifether(1),p-hydroxybenzaldehyde(2),diisooctyl phthalate(3),psoracorylifol G(4),psoracorylifol H(5),bisbakuchiol V(6),bisbakuchiol I(7),bisbakuchiol H(8),bisbakuchiol F(9),bisbakuchiol D(10),bisbakuchiol G(11),stigmasterol(12),bavachalcone(13),psoralidin(14),bavachinin(15),isopsoralen(16),psoralen(17),stigmasterol-3-O-β-D-glucopyranosyl-6′-O-palmitate(18),4-hydroxylonchocarpin(19),neocorylin(20),and 6-prenylnaringenin(21),respectively.Conclusion Compounds 1,4,5,and 6 are four new compounds.
