Application of schizandrin A in detection of cytochrome P4503A enzymatic activity and detection method thereof

The invention provides application of schizandrin A in detection of cytochrome P4503A enzymatic activity and a detection method thereof. The schizandrin A can be used as probe substrate to detect the cytochrome P4503A enzymatic activity, and the schizandrin A or other medicines are used as specific probe substrate to obtain schizandrin to be used as metabolite at the reaction temperature between 10 DEG C and 60 DEG C. The decrement of the schizandrin A substrate or the metabolite generation amount of the schizandrin A is used as an evaluation index of cytochrome P4503A subfamily enzymatic activity. Or a mammal to be detected is enabled to take the schizandrin A or other medicines with 0.01-1000mg/kg of weight of the mammal through an intravenous injection, muscle injection or oral way; a time point is selected within 0-72h, and then a biological sample of blood plasma, urine, excrement or bile of the mammal to be detected is collected; and the decrement of the schizandrin A substrate or the metabolite generation amount of the schizandrin A is measured to be used as the evaluation index of the cytochrome P4503A subfamily enzymatic activity.
