蝉翼藤根中木质素苷及蔗糖酯成分研究
运用硅胶、MPLC和制备HPLC等柱色谱方法对蝉翼藤根的化学成分进行分离,并通过理化性质和MS、NMR波谱数据进行结构鉴定.从蝉翼藤根的95%乙醇提取物中分离鉴定了9个化合物,包括5个木质素苷acernikol-4″-O-β-D-glucopyranoside (1), (7R, 8S)-dihydrodehydrodiconiferyl alcohol 9-O-β-D-glucopyranoside (2), (7R, 8S)-dihydrodehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (3), (7R, 8S)-dihydrodehydrodiconiferyl alcohol 9'-O-β-D-glucopyranoside (4), (7R, 8S)-5-methoxydihydrodehy drodiconiferyl alcohol 4-O-β-D-glucopyranoside (5);3个蔗糖酯3, 6'-O-diferuloylsucrose (6), 3-O-feruloyl-6'-O-sinapoylsucrose (7), sibricose A5 (8);1个有机酸酯mehyl ferulate(9).化合物1~5,8, 9为首次从蝉翼藤属中分离得到.采用MTT法测定了化合物对肺癌细胞株A549、宫颈癌细胞株Hela和乳腺癌细胞株MCF-7的细胞毒活性.结果表明化合物2,3和7对所测试的人源肿瘤细胞具有较弱的抑制活性.
