‘Okra’ Hibiscus esculentus L.: A study of its hepatoprotective activity

In the present study, an attempt has been made to validate the claimed uses of ‘Okra’ Hibiscus esculentus in liver diseases. The preventive action of ethanolic extract of okra (EEO) against liver injury was evaluated in rodents using carbon tetrachloride-induced hepatotoxicity model. EEO, at 250 and 500 mg/kg body weight, exerted significant dose-dependent hepatoprotection by decreasing the CCl4-induced elevation of serum SGOT, SGPT, ALP, GGT, cholesterol, triglycerides and malondialdehyde (MDA) non-protein sulfhydryls (NP-SH) and total protein (TP) levels in the liver tissue. A significant reduction was also observed in pentobarbital-induced sleeping time in mice. The hepatoprotective and antioxidant activities of the extract are being comparable to standard silymarin. These findings were supported by histological assessment of the liver biopsy. The ability of okra extract to protect chemically induced liver damage may be attributed to its potent antioxidant property
