Free radical scavenging and hepatoprotective potential of Ficus microcarpa L. fil. bark extracts

Successive extracts of Ficus microcarpa L. fil. bark (FMB) were tested for antioxidant and hepatoprotective activity against carbon tetrachloride- and paracetamol-induced hepatotoxicities in rats. The ethyl acetate extract of FMB exhibited significant antioxidant and hepatoprotective activity by reducing carbon tetrachloride- and paracetamol-induced changes in biochemical parameters as evidenced by enzymatic and histological examination. Pretreatment with ethyl acetate extract of FMB significantly shortened the duration of pentobarbitone-induced necrosis in mice, indicating its hepatoprotective potential. Phytochemical studies confirmed the presence of the phenolic compound, catechin, in FMB, which may interfere with free-radical formation and may account for its significant hepatoprotective effects. The present study thus provides a scientific rationale for the traditional use of this plant in the management of liver disorders.
