Abstract:

Methyleugenol (1), one of the main bioactive constituents of the seeds of Myristica fragrans Houtt. (family: Myristicaceae),was incubated with rat hepatic microsomes from rats pretreated with sodium phenobarbital. Eight biotransformation products named (R)-1'-methoxymethyleugenol (2), 3-(3,4-dimethoxyphenyl)-l-methoxyprop-2-ene (3), cis-3,4-dimethoxycinnamyl acetate (4), trans-3,4-dimethoxycinnamyl acetate (5), (R)-1'-hydroxymethyleugenol (6), trans-3,4-dimethoxycinnamyl alcohol (7), cis-3,4-dimethoxycinnamyl alcohol (8), and (R)-3-(3,4-dimethoxyphenyl)-propane-1,2-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.

Key words: Methyleugenol, Myristica fragrans, Biotransformation, Rat hepatic microsomes
