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.
Twenty one compounds were isolated from the ethanol extract of Polygonum perfoliatum.They were identifi ed as 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）on the basis of spectral data. Among them, compounds 1~19 （except 4, 5 and 12） were isolated from this plant for the first time, and compounds 1-11 （except 4 and 5） and 17-19 were obtained from this genus for the first time.
