Abstract:

Hepatic fibrosis, characterized by extracellular matrix accumulation, is the common cause of chronic liver failure and is a leading cause of morbidity and mortality worldwide. The aim of the present study was to evaluate the effect of dried flowers of Woodfordia fruticosa on carbon tetrachloride (CCl4)-induced hepatic fibrosis in rat model. Hepatic fibrosis was induced in male Wistar rats by CCl4 administration (150μl/100 g rat weight, oral) twice a week for 10 weeks. In preventive model, administration of daily doses of methanolic extract of W. fruticosa (MEWF) at two different doses (100 mg/kg, body weight (b.w.) and 200 mg/kg, b.w.) was started 1 week before the onset of CCl4 administration and continued for 10 weeks. In curative model, MEWF at 100 and 200 mg/kg were given for last 2 weeks after the establishment of fibrosis. MEWF at a dose of 200 mg/kg was able to exert a more pronounced effect as evidenced histologically by significant reduction in fibrotic septa formation in liver tissue, immunohistochemically by abridged expression of collagen III, and also biochemically by serum and tissue antioxidant status, lipid peroxidation, and hydroxyproline level. Liquid chromatography-mass spectrometry analysis revealed the presence of confertin, quercetin methyl ether, ellagic acid, and stigmasterol in MEWF, which could be responsible for its antifibrotic activity. These results indicate the effective protection exerted by MEWF against CCl4-induced hepatic fibrosis in a dose-dependent manner.
