Screening of liver protective effect of ethanolic leaf extract of Callicarpa lanata (EECL) in ethanol induced hepatotoxicity in wister rats

Background The ethanolic extract of Callicarpa lanata (EECL), belonging to the family Verbenaceae, were studied for hepatoprotective activity in Wister rats with liver damage induced by ethanol.

Methods Ethanol treated rats showed significant increase in the levels of serum enzyme activities, total bilirubin and reduction in total proteins reflecting the liver injury caused by ethanol. EECL, at a dose of 400 and 200mg/kg body weight exhibited hepatoprotective effect by lowering the Serum Glutamate Pyruvate Transaminase (SGPT), Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Alkaline Phosphate (SALP), Gama Glutamyl Transpeptidase (GGTP), total Bilirubin to a significant extent and also significantly increased the levels of total protein in a dose dependent manner.

Results The results were highly significant at dose level of 400mg/kg body weight (p <0.01) and significant at dose level of 200mg/kg body weight (p <0.05). The effects of EECL at both levels were comparable with standard drug silymarin. The hepatoprotective activity was also supported by histopathological studies of liver tissue.

Conclusions In-vivo hepatoprotective activity of ethanolic leaf extract of Callicarpa lanata (EECL) against Ethanol induced acute liver injury in rats showed significant results in a dose dependent manner.
