Objective:
To study the hepatotoxicity effects in rats with different extract of Fructus Gardeniae.
Method:
Observe the change of appearance, behavior and weight of rats through oral gavage daily for 3 d. Weigh the liver and calculate the liver index. Detect the ALT, AST and TBIL. Observe the liver tissue by optical microscope.
Result:
The weight and index of liver were increased by 3.08 g x kg(-1) aqueous extract, 1.62 g x kg(-1) alcoholic extract and 0.28 g x kg(-1) geniposide, compared to those of the blank group (P < 0.005, P < 0.001) and the activities of ALT, AST and the content of TBIL were also increased, compared to those of the blank group (P < 0.05, P < 0.001). The liver cells were obviously swell, necrotic and changed with inflammatory infiltrate.
Conclusion:
Aqueous extract, alcoholic extract and geniposide displayed hepatotoxicity, and the geniposide which was the main substance of the Fructus Gardeniae might be mainly responsible for the hepatotoxicity.
