甲基丁香酚(1)是中药肉豆蔻的主要成分之-,将其与大鼠肝微粒体共温孵,从温孵物中通过色谱方法得到原形化合物1和8个转化产物(2-9),根据谱学数据并与文献报道数据比较,确定它们分别为(R)-1-甲氧基甲基丁香酚(2)、3-(3,4-二甲氧基苯基)-1-甲氧基-2-丙烯(3)、顺式-3,4-二甲氧基桂皮酰乙酯(4)、反式-3,4-二甲氧基桂皮酰乙酯(5)、(R)-1-羟基甲基丁香酚(6)、反式-3,4-二甲氧基桂皮醇(7)、顺式-3,4-二甲氧基桂皮醇(8)、僻)-3-(3,4-二甲氧基苯基)-丙烷-1,2。二醇(9)。化合物7和8的13C NMR数据为首次报道。本文结果为甲基丁香酚的应用提供了有用的信息。
Methyleugenol (1), one of the main bioactive constituents of the seeds of Myristicafragrans Houtt. (family: Myristicaceae), was incubated with rat hepatic microsomes from rats pretreated with sodium phenobarbital. Eight biotransformation products named (R)-l'-methoxymethyleugenol (2), 3-(3,4-dimethoxyphenyl)-l-methoxyprop-2-ene (3), cis-3,4-dimethoxycinnamyl acetate (4), trans-3,4-dimethoxycinnamyl acetate (5), (R)-I hydroxymethyleugenol (6), trans-3,4-dimethoxycinnamyl alcohol (7), cis-3,4-dimethoxycinnamyl alcohol (8), and (R)-3-(3,4-dimethoxyphenyl)-propane-l,2-diol (9) were obtained and their structures were elucidated by NMR and MS data analysis and by comparison with the previously reported data. The biotransformation of 1 may provide valuable information for the use of methyleugenol. The NMR data of compounds 4 and 6 were reported for the first time.
