Hepatoprotective effect of ethanol extract from Berchemia lineate against CCl4-induced acute hepatotoxicity in mice

Abstract

Context: The roots of Berchemia lineate (L.) DC. (Rhamnaceae) have been long used as a remedy for the treatment of some diseases in Guangxi Province, China. Objective: The present study investigates the hepatoprotective effect of Berchemia lineate ethanol extract (BELE) on CCl4-induced acute liver damage in mice. Materials and methods: Effect of BELE administrated for 7 consecutive days was evaluated in mice by the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), albulin (ALB), globulin (GLB), and total protein (TP) levels, as well as liver superoxide dismutase (SOD) activity and malondialdehyde (MDA) level. Moreover, histopathological examinations were also taken. Results: Compared with the model group, administration of 400 mg/kg BELE for 7 d in mice significantly decreased the serum ALT (56.25 U/L), AST (297.67 U/L), ALP (188.20 U/L), and TBIL (17.90 mol/L), along with the elevation of TP (64.67 g/L). In addition, BELE (100, 200, and 400 mg/kg, i.g.) treated mice recorded a dose-dependent increment of SOD (291.17, 310.32, and 325.67 U/mg prot) and reduction of MDA (7.27, 6.77, and 5.33 nmol/mg prot) levels. Histopathological examinations also confirmed that BELE can ameliorate CCl4-induced liver injuries, characterized by extensive hepatocellular degeneration/necrosis, inflammatory cell infiltration, congestion, and sinusoidal dilatation. Discussion and conclusion: The results indicated that BELE possessed remarkable protective effect against acute hepatotoxicity and oxidative injuries induced by CCl4, and that the hepatoprotective effects of BELE may be due to both the inhibition of lipid peroxidation and the increase of antioxidant activity.
