RESUMO
Abstract The hypolipidemic activity of friedelin isolated from Azima tetracantha Lam., Salvadoraceae, was studied in Triton WR-1339 and high-fat diet-induced hyperlipidemic rats. In Triton WR-1339 induced hyperlipidemic rats, treatment with friedelin (50 and 70 mg/kg) showed a significant (p < 0.01) lipid-lowering effect as assessed by reversal of plasma levels of total cholesterol (TC), triacylglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). In high-fat diet fed hyperlipidemic rats, treatment with friedelin (50 and 70 mg/kg) caused lowering of lipid levels in plasma and liver. The hypolipidemic activity of friedelin was compared with fenofibrate, a known lipid-lowering drug, in both models.
