杠板归的化学成分

摘要：

采用柱层析方法从蓼科药用植物杠板归(Polygonum Perfoliatum)分离了21个化合物(1～21),通过MS与NMR数据鉴定这些化合物为α-tocopherolquinone (1), 7'-dihydroxymatairesinol (2), (24S)-24-ethylcholesta-3β,5α,6α-triol (3), 4-dihydroxy-5,7-dihydroxy-4-(4-hydroxyphenyl) coumarin (4), quercetin (5), cucurbitacin Ⅱa (6), cucurbitacin U (7), iotroridoside A (8), pokeweedcerebroside 5 (9), bonaroside (10), helonioside A (11), helonioside B (12), lapathoside D (13), vanicoside B (14), vanicoside C (15), vanicoside F (16), asteryunnanoside F (17), saikosaponin M (18), hydropiperoside (19), quercetin-3-O-β-D-glucuronide-6"-butyl ester (20), quercetin-3-O-β-D-glucuronide-6"-methyl ester (21). 化合物1～19(除4,5,12)为首次从该植物中分离得到,化合物1～11(除4,5)和17～19为首次从该属植物中分离得到.图1参22
