Biotransformation of (−)-Menthone by Human Liver Microsomes [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 2006
The aim of the current study was to investigate the metabolism of (-)-menthone by liver microsomes of humans. (-)-Menthone (1) was metabolized to (+)-neomenthol (2) (3-reduction) and 7-hydroxymenthone (3) by human liver microsomes. The metabolites formed were analyzed on GC and GC-MS.
