Abstract The hepatoprotective potential of Lygodium flexuosum (L.) Sw. was evaluated in male Wistar rats against carbon tetrachloride-induced liver damage in preventive and curative models. Toxic control and n-hexane extract-treated rats received a single dose of CCl4 (150 microL/100g, 1:1 in corn oil). Pre-treated rats were given n-hexane extracts at 200 and 100 mg/kg dose 48, 24 and 2 h prior to CCl4 administration. In post-treatment groups, rats were treated with n-hexane extract at a dose of 200 and 100 mg/kg, 2, 24 and 48 h after CCl4 intoxication. Rats pre-treated with Lygodium flexuosum remarkably prevented the elevation of serum AST, ALT, LDH and liver lipid peroxides in CCl4-treated rats. Rats treated with the extract after the establishment of CCl4 induced liver injury showed significant (p < or = 0.05) protection of liver as evidenced from normal AST, ALT, LDH and MDA levels. Hepatic glutathione levels were significantly (p < or = 0.05) increased by the treatment with the extracts in both the experimental groups. Histopathological changes induced by CCl4 were also significantly (p < or = 0.05) reduced by the extract treatment in preventive and curative groups. Phytochemical studies revealed the presence of saponins, triterpenes, sterols and bitter principles in Lygodium flexuosumn-hexane extract which could be responsible for the possible hepatoprotective action.
