摘 要:采用硅胶柱色谱、制备型MPLC以及制备型HPLC等多种色谱技术,从山豆根中分离得到12个化合物,根据化合物的理化性质及波谱数据(1H,13C-NMR)分析,分别鉴定为3-(4-hydroxyphenyl)-4-(3-methoxy-4-hydroxyphenyl)-3,4-dehydroquinolizidine(1),lanatine A(2),cermizine C(3),senepodine G(4),senepodine H(5),jussiaeiine A(6),jussiaeiine B(7),(+)-5α-hydroxyoxysophocarpine(8),(-)-12β-hydroxyoxysophocarpine(9),(-)-clathrotropine(10),(-)-cytisine(11)和(-)-N-methylcytisine(12),化合物1~7首次从槐属植物中分离得到。通过抗病毒活性筛选发现化合物1,3,6~10具有抗柯萨奇病毒B3型(CVB3)活性,IC_(50)介于0.12~6.40,SI(SI=TC_(50)/IC_(50))介于5.6~50.1。抗菌活性筛选发现化合物1,3,7具有抑制金黄色葡萄球菌(ATCC 29213)的活性,MIC分别为8.0,3.5,6.0 g·L^(-1);化合物1,3,7,12具有抑制金黄色葡萄球菌(ATCC33591)的活性,MIC分别为18.0,7.5,8.0,12.0 g·L^(-1)。化合物2,6,7具有抑制大肠埃希菌(ATCC 25922)的活性,MIC分别为1.0,3.2,0.8 g·L^(-1)。Twelve quinolizidine alkaloids were isolated from Sophora tonkinensis by means of silica gel,preparative MPLC,and preparative HPLC. On analysis of NMR spectroscopic data,their structures were established as 3-( 4-hydroxyphenyl)-4-( 3-methoxy-4-hydroxyphenyl)-3,4-dehydroquinolizidine( 1),lanatine A( 2),cermizines C( 3),senepodines G( 4),senepodines H( 5),jussiaeiines A( 6),jussiaeiines B( 7),( +)-5α-hydroxyoxysophocarpine( 8),(-)-12β-hydroxyoxysophocarpine( 9),(-)-clathrotropine( 10),(-)-cytisine( 11),and(-)-N-methylcytisine( 12),respectively. Compounds 1-7 were first isolated from Sophora L. plant.In the in vitro assays,the isolated compounds 1,3,6-10 exhibited potent activity against CVB3 with IC_(50) of 6. 40,3. 25,4. 66,3. 21,0. 12,0. 23 and 1. 60,and with selective index values( SI = TC_(50)/ IC_(50)) of 12. 0,5. 6,13. 0,15. 1,50. 1,26. 2,and 23. 6,respectively. Compounds 1,3,and 7 exhibited activity against staphylococcus aureus( ATCC 29213) with MIC values of 8. 0,3. 5,6. 0 g·L^(-1),respectively. Compounds 1,3,7,and 12 exhibited activity against staphylococcus aureus( ATCC 33591) with MIC values of18. 0,7. 5,8. 0,12. 0 g·L^(-1),respectively. Compounds 2,6,7 exhibited activity against Escherichia coli( ATCC 25922) with MIC values of 1. 0,3. 2,0. 8 g·L^(-1)。
