摘    要:目的:对味噌含氮类化学成分进行系统研究。方法采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱、MCI柱色谱、反相C18硅胶柱色谱及PHPLC等方法进行分离纯化,根据化合物的理化性质和波谱数据(1 H-NMR、13 C-NMR、HMBC、MS)进行结构鉴定。结果从味噌中分离并鉴定了17个含氮类化合物,它们依次为:环-(亮氨酸-酪氨酸)(1)、环-(苯丙氨酸-酪氨酸)(2)、环-(脯氨酸-甘氨酸)(3)、焦谷氨酸甲酯(4)、尿嘧啶(5)、胸腺嘧啶(6)、N-乙酰苯丙氨酸(7)、酪氨酸(8)、苯丙氨酸(9)、苯丙氨酸甲酯(10)、N-甲基亮氨酸(11)、异亮氨酸(12)、缬氨酸(13)、亮氨酸(14)、谷氨酸(15)、甘氨酸(16)和天冬氨酸(17)。结论化合物1~17均为首次从味噌中分离得到;化合物1~3为首次从大豆或大豆产品中分离得到的环肽。

关 键 词:味噌  环肽  氨基酸  化学成分

Abstract:Objective To investigate the nitrogenous chemical constituents of Weiceng .Methods Weiceng extract was subjected to various column chromatography and spectroscopic methods were used for the elucidation of compounds .Results Seventeen compounds were isolated and identified as cyclo-(Leu-Tyr)(1), cyclo-(Phe-Tyr) (2), cyclo-(Pro-Gly) (3), L-Pyroglutamic acid methyl ester (4), uracil (5), thymine (6), N-acetylphenylalanine (7), tyrosine (8), phenylala-nine (9), phenylalanine methyl ester (10), N-methyl leucine (11), isoleucine (12), valine (13), leucine (14), glutamic acid (15), glycine (16) and aspartic acid (17).Conclusion All the seventeen compounds are isolated from Weiceng for the first time .Before this study , cyclopeptides 1-3 have never been isolated from soy bean or its products .
Keywords:Weiceng  cyclopeptides  amino acids  chemical constituent
