目的:对菊科植物红花(carthmus tinctorius L.)的干燥花的化学成分进行研究。方法:运用硅胶柱色谱﹑Sephadex LH-20柱色谱﹑ODS柱色谱、制备HPLC等分离手段进行化学成分的分离纯化,根据理化性质及波谱数据鉴定其结构。结果:从红花体积分数70%乙醇水溶液的提取物中分离得到3个化合物,分别鉴定为(+)-松脂酚((+)-pinoresinol)(1)(+)-表松脂酚((+)-epipinoresinol)(2)槲皮素(3)结论:化合物1、2为首次从红花属植物中分离得到。
Objective: To study the chemical constituents of dried flowers of Compositae carthamus tinctorius L. Methods: The constituents were isolated and purified by silica gel column chromatography, Sephadex LH-20 column chromatography, ODS column chromatography and preparative HPLC. Their chemical structures were elucidated on the basis of physico-chemical properties and spectral data. Results: Three compounds were isolated from extracts of 70% aqueous solution of Carthamus tinctorius and identified as (+) - pinoresinol (1) (+) - ) -epipinoresinol) (2) Quercetin (3) Conclusion: Compounds 1 and 2 were isolated from the genus Cymbidium for the first time.
