Abstract
The present study investigates hepatoprotective effects of polyphenol rich Murraya koenigii L. (MK) hydro-ethanolic leaf extract in CCl4 treated hepatotoxic rats. Plasma markers of hepatic damage, lipid peroxidation levels, enzymatic, and non-enzymatic antioxidants in liver and histopathological changes were investigated in control and treated rats. MK pretreated rats with different doses (200, 400 and 600mg/kg body weight) showed significant decrement in activity levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total protein, and bilirubin. Also, MK treated rats recorded a dose dependent increment in hepatic super oxide dismutase, catalase, reduced glutathione and ascorbic acid and, a decrement in lipid peroxidation. Microscopic evaluations of liver revealed CCl4-induced lesions and related toxic manifestations that were minimal in liver of rats pretreated with MK extract. These results demonstrate that hydro-ethanolic leaf extract of MK possesses hepatoprotective potentials.
