吉祥草化学成分的分离与鉴定

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。

The chemical constituents from whole plant of Reineckia carnea(Andr.)Kunth

Objective To isolate the constituents of the whole plant of Reineckia carnea(Andr.)Kunth and identify their structures. Methods The compounds were isolated by chromatography on silica gel column,sephadex LH-20 and reverse phase pre-HPLC,and identified on the basis of physicochemical constants and spectral analysis. Results Eight compounds were identified as:Diosphenol( 1),N-benzoyl-L-phenylalaninol( 2),daidzein( 3),3′-hydroxydaidzein( 4),bis(2-ethylhexyl)phthalate( 5),1,2-Benzenedicarboxylic acid,dibuty ester( 6),syringaresinol( 7),ciwujiatong( 8). Conclusions Compound 1 is isolated from the nature for the first time and compounds 28 are isolated from Reineckia genus for the first time.
