亚麻根的化学成分研究

目的:研究亚麻根Linum usitatissimum的化学成分.方法:运用硅胶柱色谱进行分离纯化,通过理化性质和波谱分析鉴定结构.结果:从中分离鉴定了10个化合物,分别为香草酸(vanillic acid,1),丁香酸(syringic acid,2),黄嘌呤(xanthine,3),牡荆苷(vitexin,4),异香草醛(isovanillin,5),(E)-3,3'-二甲氧基-4,4'-二羟基-1,2-二苯乙烯(E)-3,3'-dimethoxy-4,4'-dihydfoxystilbene,6],2-甲氧基对苯二酚-4-β-D-吡喃葡萄糖苷(tachioside,7),β-谷甾醇和豆甾醇(8和9)混合物,盐酸小檗碱(berberine chloride,10).结论:化合物1～3,5～7,10是首次从该植物中分离得到.

Studies on chemical constituents of roots of Linum usitatissimum

Objective: To study the chemical constituents from the roots of Linum usitatissimum.  Method: The compounds were isolated and purified by silica gel column chromatography, their structures were elucidated by physico chemical properties and spectroscopic data.  Result: Ten compounds were isolated and identified as vanillic acid (1), syringic acid (2), xanthine (3), vitexin (4), isovanillin (5), (E) 3, 3′ dimethoxy 4,4′ dihydroxystilbene (6), tachioside (7), β sitosterol and stigmasterol (8 and 9) mixture,berberine (10).  Conclusion: Compounds 1 3, 5 7, 10 were isolated from L. usitatissimum for the first time.
