杠板归的化学成分(英文)

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),pokeweedcerebroside5(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.
