摘要
对吉祥草根茎中所含化学成分进行研究.方法采用反相硅胶柱色谱、RP-HPLC等各种色谱技术进行分离和纯化,再通过化合物的理化性质和波谱解析鉴定结构.从吉祥草中分离到2个甾体皂苷及2个苯丙素类化合物,经鉴定其结构分别为(25S)-22,3-dihydroxy-5β-furost-3β,26-diol-26-O-β-D-glucopyranosid(1)、26-O-β-D-glucopyranosylfurostane-3β,26-diol-3-O-β-D-glucopyranoside(2)、1-O-(6-O-α-L-rhamnopyranosyl-β-D-glucopyranosyl)-2-hy-droxy-4-allylbenzene(3)、落叶松树脂醇-9-O-β-D-吡喃型葡萄糖苷(4).化合物1~4均为首次从该属植物中分离得到.
The chemical constituents of Reineckia Carnea are studied. The compounds are isolated by raversed-phase silica gel column chromatography and preparative HPLC. The structures are identified by vari- ous spectroscopic methods and chemical evidences. Four Compounds(25S)-22,3-dihydroxy-5βfurost-3β, 26- diol-26-O-β-D-gluco pyranoside (1), 26-O-β-D-glucopyranosylfurostane-3β, 26-diol-3-O-β-D- glucopyranoside ( 2 ), 1-O- ( 6-O-a-L-rhamnopyranosyl-β-D-glucopyranosyl )-2-hydroxy-4-allylbenzene ( 3 ), Lariciresinol-9-O-β-D- glucopyranoside(4). Compounds 1-4 are isolated from Reineckia Carnea for the first time.
