摘 要:目的对八角莲(Dysosma versipellis)愈伤组织中木脂素类化学成分进行研究。方法以体积分数95%乙醇对八角莲愈伤组织进行提取,提取物经三氯甲烷、乙酸乙酯萃取,采用硅胶柱色谱、Sephadex LH-20凝胶色谱、制备薄层色谱等色谱技术进行分离,利用NMR、MS等光谱学方法进行结构鉴定。结果从八角莲愈伤组织中共分离鉴定了9个木脂素类化合物,分别为4'-去甲基鬼臼毒酮(1),β-足叶草脂素(2),4'-去甲基异鬼臼苦酮(3),(+)-松脂酚(4),α-足叶草脂素(5),鬼臼毒素(6),NC 370(7),4'-去甲基鬼臼毒素(8),去氧鬼臼毒素(9)。结论除化合物6外,其他化合物均为首次从八角莲愈伤组织中分离得到,化合物3,4,7为首次从该属植物中分离得到。OBJECTIVE To study the lignans constituents from callus culture of Dysosma versipellis (Hance) M. cheng ex Ying. METHODS The callus cultures of Dysosma versipellis were extracted with 95 % ethanol, and then partitioned by chloroform and ethyl acetate. The constituents were isolated from the extract by silica gel column, Sephadex LH -20, preparative thin-layer chromatography and other chromatographic separation techniques. Their structures were elucidated by NMR, MS and other spectroscopic methods. RESULTS Nine lignans were isolated and identified as 4'-demethylpodophyllotoxone ( 1), ,β-peltatin (2), 4'-demethylisopicropodophyllone (3), ( + )-pinoresinol (4), α-peltatin (5), ( - )-podophyllotoxin (6), NC 370 (7), 4'-O-demethylpodophyllotoxin (8) and desoxypodophyllotoxin (9). CONCLUSION All the compounds except compound 6 are isolated from callus culture of Dysosma versipellis for the first time, and compounds 3, 4, and 7 are for the first time obtained from the genus Dysosma.
