Hepatoprotective effect of leaf extracts from Citrus hystrix and C. maximaagainst paracetamol induced liver injury in rats
The present investigation is aimed to evaluate the hepatoprotective effects of Citrus hystrix and Citrus maxima (Red and White variety) methanolicleaf extracts on paracetamol induced toxicity. Leaf extracts were given in the dose of 200 mg/kg body weight for 7 days and toxicity was inducedby paracetamol (2 g/kg) on day 5. Silymarin (100 mg/kg body weight) was used as reference standard. On the 7th day animals were sacrificed andliver function markers (ALT, AST, ALP), total bilirubin and total protein in blood serums and hepatic antioxidants (SOD, CAT, GSH and GPx) inliver homogenate were estimated. The leaf extracts restored the liver function markers and hepatic antioxidants to the normal level than elevatedlevels noticed on paracetamol control at P < 0.001. Reversal of hepatoarchitecture has also been registered. The present study shows that C. hystrixand C. maxima leaf extracts possess hepatoprotective action against paracetamol induced hepatotoxicity.
