    Abstract:
    UHPLC-QTOF/MS technique was used to study the differences of lignans and their metabolites derived from Schisandra chinensis and vinegar Schisandra chinensis in rat plasma, bile, urine and faeces by the data processing techniques such as the dynamic background subtract(DBS), mass defect filtering(MDF) and enhance peak list (EPL) in analysis. In order to enhance accuracy for Schisandra chinensis hepatoprotective effect, we established rat acute alcoholic liver injury model in this experiment, and studied the prototype components and metabolisms of Schisandra lignans in vivo under pathological condition. The main ingredients of alcohol extract are lignans, including deoxyschizandrin, schisandrin B, schizandrin C, schizandrol, schizandrol B,schisantherin, schisantherin B, schisanhenol, gomisin G, gomisin J. The metabolic transformation of lignans in rats was mainly induced by methylation, hydroxyl, oxidation, and so on. Finally, we identified 6 kinds of prototype components and their 20 potential metabolites in Schisandra chinensis group and vinegar Schisandra chinensis group.
