摘要
为了解大叶山楝(Aphanamixis grandifolia Bl.)根中的抗肿瘤活性成分,利用各种色谱技术从其95%乙醇提取物中分离得到9个化合物,经波谱分析分别鉴定为:7-hydroxycadalene(1)、dregeana-1(2)、4-oxopinoresinol(3)、4-ketopinoresinol(4)、6-deoxyjacareubin(5)、schleicheol 1(6)、豆甾醇(7)、β-谷甾醇(8)和胡萝卜苷(9)。其中化合物1~6为首次从山楝属植物中分离得到,并首次报道了化合物1的碳谱数据。生物活性测试结果表明,化合物1和5对慢性髓原白血病细胞K562有生长抑制活性,化合物1、5和6对人胃癌细胞SGC-7901有生长抑制活性。
In order to understand the antitumor active ingredients of Aphanamixis grandifolia Bl., nine compounds were isolated from 95% ethanol extract of its roots. They were identifi ed as 7-hydroxycadalene(1), dregeana-1(2), 4-oxopinoresinol(3), 4-ketopinoresinol(4), 6-deoxyjacareubin(5), schleicheol 1(6), stigmasterol(7), β-sitosterol(8), and daucosterol(9) on the basis of spectral data. Compounds 1– 6 were isolated from the genus Aphanamixis for the fi rst time, and the 13 C NMR spectral data of compound 1 was reported for the fi rst time. Compounds 1 and 5 showed inhibition of the proliferation of K562 cell line, and compounds 1, 5 and 6 possessed inhibitory activity against SGC-7901 cell line.
