J Oleo Sci. 2011;60(3):127-32.The in vitro metabolism of (+)-(1S,3S,4R) and (-)-(1R,3R,4S)-menthol enantiomers was examined by incubation with human liver microsomes, and the oxidative metabolites thus formed were analyzed using gas chromatography-mass spectrometry (GC-MS). The (+)- and (-)-menthols were found to be oxidized to the respective (+)-(1S,3S,4S)- and (-)-(1R,3R,4R)-trans-p-menthane-3,8-diol derivatives by human liver microsomal P450 enzymes. Read More
