从楝科植物山楝(Khaya senegalensis)的甲醇提取物中分离得到两个柠檬苦素类化合物,经MS和NMR鉴定其结构分别为3α,7 α-dideacetylkhivorin(1)和1-O-acetylkhayanorin B(2)。利用1D和2D NMR(包括DEPT、1H-1H COSY、HMQC、HMBC实验)对化合物1和2的1H和13 C化学位移进行了完全归属。化合物1对MCF-7、SiHa和Caco-2细胞显示出显著的生长抑制活性,IC 50值在0.07-0.14 µm(35-69 ppm)范围内,而化合物2则没有。版权所有© 2007约翰威利父子有限公司
Two limonoids were isolated from the methanol extract ofKhaya senegalensis(Meliaceae), and their structures were identified as 3α,7α‐dideacetylkhivorin (1) and 1‐O‐acetylkhayanolide B (2) on the basis of MS and NMR spectral data. Complete assignments of1H and13C chemical shifts for compounds 1 and 2 were achieved by means of 1D and 2D NMR including DEPT,1H‐1H COSY, HMQC, HMBC experiments. Compound 1 showed significant growth inhibitory activities against MCF‐7, SiHa and Caco‐2 cells with IC50values in the range of 0.07–0.14 µm(35–69 ppm) while compound 2 did not.
