目的对吉祥草的化学成分进行分离与鉴定。方法采用反复硅胶柱色谱、Sephadex LH-20、高效液相制备等方法分离纯化,所得化合物通过理化常数测定及光谱分析等手段鉴定其化学结构。结果分离得到8个化合物,分别为diosphenol(1)、N-benzoyl-L-phenylalaninol(2)、大豆素(daidzein,3)3、’-羟基大豆苷元(3’-hydroxydaidzein,4)、bis(2-ethylhexyl)phthalate(5)、邻苯二酸二正丁基酯(1,2-Benzenedicarboxylic acid,dibuty ester,6)、丁香脂素(syringaresinol,7)、刺五加酮(ci-wujiatong,8)。结论化合物1为新的天然产物2,-8为首次从该属植物中分离得到。 Objective To isolate and identify the chemical constituents of auspicious grass. Methods The compounds were separated and purified by repeated silica gel column chromatography, Sephadex LH-20 and HPLC. The chemical structures of the compounds were identified by physical and chemical constants and spectral analysis. Results Eight compounds were isolated and identified as diosphenol (1), N-benzoyl-L-phenylalaninol (2), daidzein 3, 3’-hydroxydaidzein 4 2-ethylhexyl phthalate (5), 1,2-Benzenedicarboxylic acid (dibuty ester, 6), syringaresinol (7), ci-wujiatong ,8). Conclusion Compound 1 is a new natural product, 2 and 8 were isolated from this genus for the first time.
