Abstract
The study aimed to evaluate the hepatoprotective potential of aqueous extract of Tamarindus indica fruit against combination of two antitubercular drugs viz. Isoniazid and Rifampicin induced hepatotoxicity in rats. In vitro antioxidant activity of aqueous extract of T. indica by DPPH-HPLC method was found to be 81.48%. Treatment with aqueous extract of T. indica significantly reduced the elevated levels of biochemical markers such as SGOT, SGPT, ALP, bilirubin, TBARS and increased the albumin level as well antioxidant activities of SOD, CAT and GSH in intoxicated rats. The biochemical changes were supported by histological observations. Results of this study clearly demonstrate that aqueous extract of T. indica fruit protects against anti tuberculosis induced oxidative liver damage in rats and thus possess significant hepatoprotective activity. Further, it could be suggested that supplementation with this food extract might prove beneficial in the individuals on anti-TB drugs.
