摘要
综合运用正相硅胶柱色谱、反相ODS柱色谱、Sephadex LH-20凝胶柱色谱以及制备型HPLC等色谱学方法对芸香科黄皮属植物假黄皮Clausena excavata枝叶中的化学成分进行系统分离和纯化,根据分离得到化合物的波谱数据及其理化性质,并通过与文献中报道的相应化合物的波谱数据进行对照,鉴定了从假黄皮枝叶的90%乙醇提取物中分离得到的19个化合物,分别鉴定为苔色酸甲酯(1)、丁香脂素(2)、lenisin A(3)、东莨菪素(4)、欧前胡素酚(5)、N-benzoyltyrarnine methyl ether(6)、N-p-coumaroyltyramine(7)、aurantiamide acetate(8)、1H-indole-3-carboxaldehyde(9)、furostifoline(10)、clausenalansine E(11)、3-formylcarbazole(12)、clausine L(13)、clausine E(14)、methyl carbazole-3-carboxylate(15)、glycosinin(16)、murrayafoline A(17)、clausine H(18)和2,7-dihydroxy-3-formyl-1-(3′-methyl-2′-butenyl)carbazole(19)。其中化合物1~11为首次从假黄皮中分离得到,化合物1、2、10为首次从黄皮属植物中分离得到。此外,以MH7A滑膜成纤维细胞为活性评价细胞株,采用MTS法通过评价分离鉴定的化合物1~19的体外抑制滑膜细胞增殖的活性对分离得到的化合物的抗类风湿性关节炎活性进行了评价。活性评价结果表明化合物10~19具有较为显著的抗类风湿性关节炎活性,它们对MH7A滑膜成纤维细胞增殖抑制活性的IC50为(27.63±0.18)~(235.67±2.16)μmol·L-1。
The chemical constituents from the stems and leaves of Clausena excavata were isolated and purified by column chromatography with silica gel,ODS,Sephadex LH-20 and RP-HPLC.The chemical structures of the isolated compounds were identified on the basis of physicochemical properties,spectroscopic analysis,as well as the comparisons with the data reported in literature.Nineteen compounds were isolated from the 90%ethanol extract of the stems and leaves of C.excavata,which were identified as methyl orsellinate(1),syringaresinol(2),lenisin A(3),scopoletin(4),osthenol(5),N-benzoyltyrarnine methyl ether(6),N-p-coumaroyltyramine(7),aurantiamide acetate(8),1H-indole-3-carboxaldehyde(9),furostifoline(10),clausenalansine E(11),3-formylcarbazole(12),clausine L(13),clausine E(14),methyl carbazole-3-carboxylate(15),glycosinin(16),murrayafoline A(17),clausine H(18)and 2,7-dihydroxy-3-formyl-1-(3′-methyl-2′-butenyl)carbazole(19).Among these isolated compounds,compounds 1-11 were isolated from C.excavata for the first time,and compounds 1,2 and 10 were isolated from the genus Clausena for the first time.In addition,this study evaluated the anti-rheumatoid arthritis activities of compounds 1-19 by measuring their anti-proliferative effects on synoviocytes in vitro according to MTS method.Compounds 10-19 displayed remarkable anti-rheumatoid arthritis activities,which exhibited the inhibitory effects on the proliferation of MH7 A synovial fibroblast cells with the IC50 values ranging from(27.63±0.18)to(235.67±2.16)μmol·L-1.
