摘  要:为研究常用中药爵床科植物穿心莲(Andrographis paniculata)根的化学成分,运用各种色谱方法从安徽临泉产穿心莲根的80%乙醇提取物中分离并鉴定了28个化合物,其中20个黄酮:5,5'-二羟基-7,8,2'-三甲氧基黄酮(1)、5-羟基-7,8,2',6'-四甲氧基黄酮(2)、5,3'-dihydroxy-7,8,4',-trimethoxyflavone(3)、2'-羟基-5,7,8-三甲氧基黄酮(4)、5-羟基-7,8,2',3',4'-五甲氧基黄酮(6)、wightin(7)、5,2',6'-trihydroxy-7-methoxyflavone 2'-O-β-D-glucopyranoside(8)、5,7,8,2'-四甲氧基黄酮(10)、5-羟基-7,8-二甲氧基二氢黄酮(11)、5-羟基-7,8-二甲氧基黄酮(12)、5,2'-二羟基-7,8-二甲氧基黄酮(13)、5-羟基-7,8,2',5'-四甲氧基黄酮(14)、5-羟基-7,8,2',3'-四甲氧基黄酮(15)、5-羟基-7,8,2'-三甲氧基黄酮(16)、5,4'-二羟基-7,8,2',3'-四甲氧基黄酮(17)、二氢黄芩新素(18)、andrographidine A(19)、andrographidine B(20)、andrographidine C(21)和5,2'-dihydroxy-7,8-dimethoxyflavone 2'-O-β-D-glucopyranoside(22);3个二萜内酯:新穿心莲内酯苷元(23)、新穿心莲内酯(24)和穿心莲内酯(25);2个苯丙素类:反式肉桂酸(26)和4-羟基-2-甲氧基肉桂醛(5);齐墩果酸(9),β-谷甾醇(27)和β-胡萝卜苷(28)。化合物1为新化合物,化合物4为新天然产物,化合物2、3、5为首次从该属植物中分离得到,化合物6~9为首次从该植物中分离得到。To investigate the chemical constituents of the roots of Andrographis paniculata,28 compounds were isolated and identified from the 80% ethanol extract.There are 20 flavonoids: 5,5'-dihydroxy-7,8,2'-trimetroxyflavone(1),5-hydroxy-7,8,2',6'-tetramethoxyflavone(2),5,3'-dihydroxy-7,8,4'-trimethoxyflavone(3),2'-hydroxy-5,7,8-trimethoxyflavone(4),5-hydroxy-7,8,2',3',4'-pentamethoxyflavone(6),wightin(7),5,2',6'-trihydroxy-7-methoxyflavone 2'-O-β-D-glucopyranoside(8),5,7,8,2'-tetramethoxyflavone(10),5-hydroxy-7,8-dimethoxyflavanone(11),5-hydroxy-7,8-dimethoxyflavone(12),5,2'-dihydroxy-7,8-dimethoxyflavone(13),5-hydroxy-7,8,2',5'-tetramethoxyflavone(14),5-hydroxy-7,8,2',3'-tetramethoxyflavone(15),5-hydroxy-7,8,2'-trimethoxyflavone(16),5,4'-dihydroxy-7,8,2',3'-tetramethoxyflavone(17),dihydroneobaicalein(18),andrographidine A(19),andrographidine B(20),andrographidine C(21) and 5,2'-dihydroxy-7,8-dimethoxyflavone 2'-O-β-D-glucopyranoside(22);three diterpenoids: andrograpanin(23),neoandrographolide(24) and androgra-pholide(25);two phenylpropanoids: trans-cinnamic acid(26) and 4-hydroxy-2-methoxycinnamaldehyde(5);and oleanolic acid(9),β-sitosterol(27) and β-daucosterol(28).Compound 1 is a new flavone,compound 4 is a new natural product,compounds 2,3 and 5 were isolated from the Androggraphis genus for the first time and com-pounds 6-9 were isolated from this plant for the first time.
