In the present study, hypolipidemic activity of fraction (50:50; CHCl₃:CH₃OH) of Amomum subulatum (Zingiberaceae) seeds was evaluated in cholesterol-fed rabbits. Hyperlipidemia induced by feeding atherogenic diet for 120 days resulted in a significant increase in serum total cholesterol, phospholipid and triglyceride levels when compared with control group. The levels of LDL and VLDL-cholesterol were increased significantly, but the HDL-cholesterol ratio was decreased. The changes in the antioxidant parameters were accompanied by an increase in lipid peroxidation and reduction in glutathione (GSH) and catalase activity. The level of lipid peroxidation was reduced whereas GSH content and catalase activity were elevated after the treatment with A. subulatum fraction at the dose level of 100 mg/kg.b.wt/day. A significant reduction was observed in total cholesterol, triglyceride, phospholipid, LDL and VLDL cholesterol where as HDL-cholesterol ratio was increased after administration of A. subulatum. The results of the present study indicate that fraction of A. subulatum possesses lipid-lowering and antioxidant activity and could be beneficial in the treatment of hyperlipidemia.
