摘要 对味噌中异黄酮类化学成分进行了研究。通过硅胶柱色谱、Sephadex LH-20凝胶柱色谱、反相C18硅胶柱色谱以及制备HPLC等方法,对味噌正丁醇萃取部位进行分离纯化,根据化合物的理化性质和波谱数据(1H NMR、13C NMR、HMBC、MS)鉴定单体化合物的化学结构。总共分离得到6个异黄酮类化合物(图1),分别鉴定为:染料木素(1)、大豆素(2)、黄豆黄素(3)、4',5,7,8-四羟基异黄酮(4)、4',7,8-三羟基异黄酮(5)、4',7,8-三羟基-6-甲氧基异黄酮(6)。以上化合物均为首次从味噌中分离得到。 To investigate the chemical constituents of isoflavones from wei ceng. The butanolie extract was subjected to various eolumn chromatography and speetroseopie methods were used for the elucidation of compounds. Six isoflavones were isolated and identified as genistein ( 1 ), daidzein (2), glyeitein (3) ,4', 5,7,8 -tetrahydroxy isoflavone (4),4',7, 8-trihydroxy isoflavone (5) ,4' ,7,8-tfihydroxy-6-methoxy isoflavone (6). All the six isoflavones were isolated from wei ceng for the first time.
