Abstract:
Aim Modelorganismzebrafishwasusedto study metabolites and metabolite profile of the gallic acid and protocatechuic acid of effective fractions of Polygonum capitatum,and discuss the feasibility and rationality of the model organism zebrafish in the study ofdrugmetabolism.Methods Thetwocomponents were exposed to model organism zebrafish after 24 h of solution treatment by using ultra-high performance liq-uid chromatography-quadrupole-time-of-flight tandem mass spectrometry technology (UHPLC-Q-TOF MS ) method with mass defect filter (MDF ),and the data was treated with data mining software(Metabolite Tool-sTM).Results Afterzebrafishmetabolism,themain reactions of gallic acid and protocatechuic were methyl-ation sulfated. In addition to the two parent com-pounds,six phase II metabolites were identified,in-cluding four methyl sulfate products and two sulfation products.Conclusions Themetabolismofthegallic acid and protocatechuic acid of effective fractions of Polygonum capitatum by zebrafish presents phase Ⅱmetabolites,which is highly consistent with the meta-bolic mechanism of rats.Thus it indicates the rationali-ty of the methods.At the same time,it also provides the experimental basis for clarifying the substance basis of the drug.
