OBJECTIVE To investigate effect of U.lobataleaves extract on the improvement of lipid profiles on diabetic rats.METHODS This study uses control group post test only with male Sprague dawley rats.Diabetic rats was induced by high fructose diet(HFD)and single dose streptozotocin 25mg·kg-1 bw intra peritoneal.The rat was administrated orally with water extract of U.lobataleaves in dose of 250,500 and 1000mg·kg-1 bw for 4weeks.After scarifying,blood sample was collected and then total cholesterol(TC)serum level,triglyceride(TG),low density lippoprotein(LDL)and high density lipoprotein(HDL)were examined.The data was analyzed using ANOVA test continued with LSD test(P<0.05).RESULTS The supplementation of water extract from U.lobatain dose of 250,500 and 1000mg·kg-1 bw decrease TC serum level approximately 15%,25% and 35% compared to diabetic group(P<0.05),whereas the TG was decreased by 10%,20% and 30%(P<0.05)respectively.The oral administration of U.lobataleaves extract 250,500 and 1000mg·kg-1 bw also were able to decrease LDL serum level about 30%,60% and 90%respectively compared to diabetic group(P<0.05),while the HDL serum level was increased by 40%,80% and 100%(P<0.05)respectively.In diabetic groups,HDL level serum was decreased compared to normal group(P<0.05)while the TC,TG and HDL were increased(P<0.05).CONCLUSION U.lobata leaves extract could repair lipid profiles of diabetic rats by increasing of HDL serum level,decreasing of TC serum level,TG and LDL.This potency may be related to active substances which act as an anti-cholesterolemia and antioxidant in U.lobata extract.
