47EVALUATION OF HYPOLIPIDEMIC ACTIVITY OF BETULA ALNOIDES BARK ON TRITON WR-1339 INDUCED HYPERLIPIDEMIA IN ALBINO RATSThe objective of the study was to investigate the antihyperlipidaemic effect of Betula alnoides bark in triton WR 1339 induced hyperlipidemia in rats. Triton WR 1339 (350mg kg-1, i.p.) injection significantly (p˂0.01) increased total cholesterol, triglyceride, very low density lipoprotein (VLDL), Low density lipoprotein (LDL), phospholipids and decreased high density lipoprotein (HDL). Betula alnoides showed dose dependent decrease in the total cholesterol, triglyceride, very low density lipoprotein (VLDL), Low density lipoprotein (LDL) and phospholipids. Betula alnoides increased high density lipoprotein (HDL). Administration of triton alone increased coronary risk index, atherogenic index and LDL, Betula alnoides and atorvastatin treatment decrease both the indices. It is concluded that Betula alnoides reduces total cholesterol, triglyceride, very low density lipoprotein (VLDL), Low density lipoprotein (LDL), phospholipids, coronary risk index, atherosclerotic index and increased HDL in triton induced hyperlipidemia in rats.malarsai96@gmail.comResearch422014Triton WR-1339,Betula alnoides,Coronary risk index,Hyperlipidemia,Lipid profileDominic Amal Raj A,Malarvili T,Velavan SResearch Scholar, P.G. and Research, Department of Biochemistry, Rajah Serfoji Govt.
