Abstract An on-line HPLC screening method for detection of inhibitors of human cytochrome P450 1A2 in extracts was developed. HPLC separation of extracts is connected to a continuous methoxyresorufin-O-demethylation (MROD) assay in which recombinant human P450 1A2 converts methoxyresorufin to its fluorescent metabolite resorufin. The system was tested with three P450 1A2 inhibitors, for which minimum detectable amounts (MDA) ranging from 0.7 to 9.5 ng were obtained. Analysis of a kava kava and a basil extract showed that the on-line system is applicable to complex mixtures, since in both extracts, peaks with P450 1A2 inhibiting activity were observed
