Hong (2013) Hepatoprotection of 1β-hydroxyeuscaphic acid -the major constituent from Rubus aleaefolius against CCl 4 -induced injury in hepatocytes cells, Pharmaceutical Biology, 51:6, 686-690, DOI: 10.3109/13880209.2012 caused apoptosis to cells but did not induce lipid peroxidation. Following treatment with 1b-hydroxyeuscaphic acid at doses ranging from 1 to 100 mg/mL for 24 h, cellular morphology, cell growth function (MTT assay), ALT, AST, malondialdehyde (MDA) and superoxide dismutase (SOD) were assessed and evaluated under control and exposed conditions. Results: The IC 50 of 1b-hydroxyeuscaphic acid was 15 mg/mL. Exposure of injured BRL-3A at 20 mg/mL changed abnormal size, cellular shrinkage, and enhanced regulation. ALT, AST, MDA enzyme levels were reduced and SOD activity was increased. Discussion and conclusion: Treatment with 1b-hydroxyeuscaphic acid has significant hepatoprotective activity by lowering the leakage of intracellular enzymes, reducing the oxidation of proteins and decreasing the incidence of apoptosis. These results provide a basis for confirming the traditional uses of R. aleaefolius in treating hepatic diseases.Keywords 1b-hydroxyeuscaphic acid, BRL-3A rat liver cell, hepatoprotective History
