摘要 采用硅胶、Sephadex LH-20、高效液相等色谱技术,对印楝干燥种子95%乙醇提取物的乙酸乙酯萃取部位进行了系统分离,得到8个柠檬苦素类化合物。通过与文献报道的波谱数据对比,这些化合物被鉴定为salannin(1),1-detigloyl-1-isobutylsalannin(2),salannol-3-acetate(3),salannol(4),spirosendan(5),1-detigloyloxy-3-deacetylsalannin-1-en-3-one(6),nimbin(7),6-deacetylnimbin(8)。化合物2和5为属内首次分离,并且化合物5为目前发现的唯一1个C环开裂、并与D环形成螺环结构的柠檬苦素。化合物6为新天然产物。在体外细胞毒活性筛选中,化合物6对人宫颈癌细胞(HeLa)和人白血病细胞(HL-60)具有一定生长抑制作用,IC(50)分别为(21.61±4.37)和(27.33±5.74)μmol·L^-1;7和8均对HeLa细胞表现出较弱生长抑制作用,IC(50)分别为(33.15±5.24)和(38.56±6.41)μmol·L^-1。 Eight limonoids were isolated from 95% ethanol extracts of neem( Azadirachta indica) seeds by various chromatographic methods. By comparison of their spectroscopic data with those reported in the literatures,these limonoids were determined as salannin( 1),1-detigloyl-1-isobutylsalannin( 2),salannol-3-acetate( 3),salannol( 4),spirosendan( 5),1-detigloyloxy-3-deacetylsalannin-1-en-3-one( 6),nimbin( 7) and 6-deacetylnimbin( 8). Compounds 2 and 5 were firstly isolated from this genus and 5 represented the only example of its type. And 6 is a new natural product. 6 showed inhibitory activity against He La and HL-60 cells,with IC(50) of( 21. 61 ± 4. 37) and( 27. 33 ± 5. 74) μmol·L^-1,respectively. Both 7 and 8 mildly inhibited the growth of He La cells,with IC(50) of( 33. 15 ± 5. 24) and( 38. 56 ± 6. 41) μmol·L^-1,respectively.
