摘要:
该研究从大叶山楝根95%乙醇提取物的乙酸乙酯萃取物中分离得到10个化合物,经波谱解析分别鉴定为schleicheol 2(1),β?扶桑甾醇(2),fregenedadiol(3),异巴西红厚壳素(4),丁香酯素(5),表丁香酯素(6),graminone A(7),sylvatesmin(8),Z?6?十九烯酸甲酯(9),棕榈酸(10).其中,化合物1-4、化合物7-9为首次从山楝属植物中分离得到.细胞毒活性测试结果表明,化合物1和化合物2对人胃癌细胞SGC?7901生长具有一定的抑制活性.%Aphanamixis grandifolia belongs to genus Aphanamixis of family Meliaceae.We made the experiment to clarify the constituents from the roots of A.grandifolia in this paper.The chemical constituents were isolated by silica gel,Seph?adex LH?20 column chromatographic methods.The structures were identified by spectral analysis and comparing with the previously reported literatures.The results showed that ten compounds were isolated from the ethyl acetate of ethanol ex?tract from A. grandifolia and identified respectively as schleicheol(1),β?rosasterol(2), fregenedadiol(3), isojaca?reubin(4),syringaresinol(5),episyringaresinol(6),graminone A(7),sylvatesmin(8),methyl?Z?6?nonadecenoate (9),ralmitic acid(10). The compounds 1-4,7-9 were obtained from A. grandifolia for the first time. The results of cytotoxic activity showed that compounds 1 and 2 had certain inhibitory activity on the growth of human gastric cancer cell SGC?7901.
