A method for the quantitation of three metabolites of theophylline, 1-methylxanthine (1 MX), 3-methylxanthine (3MX), and 1,3-dimethyluric acid (13DMU) in human liver microsomes has been developed. The method is based on a simple one-step extraction followed by isocratic, reversed-phase high-performance
