ABSTRACT
Objective:To explore the hepatotoxic material basis of Polygoni Multiflori Radix with zebrafish model, in order to provide a theoretical basis for the study on the mechanism of Polygoni Multiflori Radix hepatotoxicity. Method:Emodin, rhein, aloe emodin, emodin-1-O-glucoside, physcion-8-O-glucoside and aloe emodin-8-O-glucoside for three days (at the concentrations of 0.000 73, 0.002 22, 0.015 05, 0.002 36, 0.198 95, 0.072 73 g·L-1) selected from the early stage of the experiment were continuously administered to zebrafish fertilized for 72 hours to establish the liver fluorescence transgenic larvae animal model. The activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutathione (GSH) and total bilirubin (TBIL) in zebrafish at 1, 2, 3 day after administration were measured respectively, and the pathological changes of zebrafish liver tissue were analyzed. Result:Emodin, rhein, emodin-1-O-glucoside and physcion-8-O-glucoside had no significant effect on the activities of ALT, AST, GSH and content of TBIL (PPO-glucoside could significantly reduce the activities of ALT, GSH, whereas increased the content of TBIL (PPConclusion:Aloe-emodin and aloe-emodin-8-O-glucoside in Polygoni Multiflori Radix have a toxic effect on zebrafish liver, suggesting that aloe-emodin and aloe-emodin-8-O-glucoside might be the hepatotoxic material basis of Polygoni Multiflori Radix.
