川芎化学成分研究

目的：对伞形科藁本属植物川芎Ligusticum chuanxiong干燥的根茎进行化学成分研究。方法：川芎的干燥根茎用水提取,依次用醋酸乙酯,正丁醇萃取,对醋酸乙酯部分采用各种柱色谱进行分离纯化,通过波谱数据分析进行结构鉴定。结果：从醋酸乙酯部分分离11个化合物,分别鉴定为：(4S)-p-menth-1-ene-4,7diol(1),aromadendrane-4α,10β-diol(2),aromadendrane-4α,10α-diol(3),aromadendrane-4β,10β-diol(4),augustic acid(5),川芎三萜(xiongterpene,6),孕(甾)烯醇酮(pregnenolone,7),镰叶芹二醇［3(R),8(S),9(Z)-falcarindiol,8］,洋川芎内酯F(senkyunolide F,9),洋川芎内酯I(senkyunolide I,10),4-羟基-3-丁基苯肽(4-hydroxyl-3-butylphthalide,11)。结论：化合物1～5为首次从该种中分离得到。

Studies on chemical constituents of rhizomes of Ligusticum chuanxiong

OBJECTIVE: To study chemical constitutents of the rhizomes of Ligusticum chuanxiong. METHOD: The rhizomes of L. chuanxiong were extracted with water to afford a water extract which was participated between H2O and EtOAc, n-BuOH, successively. The compounds were isolatedand purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses. RESULT: Eleven compounds were isolated from the rhizomes of L. chuanxiong, and structures were characterized as (4S)-p-menth-1-ene4, 7-diol (1), aromadendrane-4alpha, 10beta-diol (2), aromadendrane-4beta, 10alpha-diol (3), aromadendrane-4beta, 10beta-diol (4), augustic acid (5), xiongterpene (6), pregnenolone (7), 3(R), 8(S), 9(Z)-falcarindiol (8), senkyunolide F (9), senkyunolide I (10), 4-hydroxyl-3-butylphthalide (11). CONCLUSION: Compounds 1-5 were obtained from the rhizomes of L. chuanxiong for the first time.
