Methods Seven probe drugs were incubated with or without methyl protodioscin respectively in human microsomes. The specific substrates used in this study were caffeine (CYP1A2), dextromethorphan (CYP2D6), tolbutamide (CYP2C9),-mephenytoin (CYP2C19), chlorzoxazone (CYP2E1), coumarin (CYP2A6) and midazolam (CYP3A4). The concentrations of the substrate metabolites (paraxanthine, dextrorphan, 4-hydroxytolbutamide, 4-hydroxymephenytoin, 6-hydroxychlor-zoxazone, 7-hydroxycoumarin and 1-hydroxymidazolam) were determined by HPLC and LC-MS/MS. Results MPD 1-10 μmolL^(-1 had no significant inhibition on the activities of the seven cytochrome P450 enzymes.
