In vitro antioxidant and antihyperlipidemic activities of Toddalia asiatica (L) Lam. leaves in Triton WR-1339 and high fat diet induced hyperlipidemic rats.Food Chem Toxicol. 2013 Oct; 60:135-40.FC
The present study was undertaken to evaluate the in vitro antioxidant and antihyperlipidemic activity of Toddalia asiatica (L) Lam. leaves in Triton WR-1339 and high fat diet-induced hyperlipidemic rats. In in vitro studies T. asiatica leaves ethyl acetate extract showed very good scavenging activity on 2,2-diphenyl-picrylhydrazyl (DPPH) (IC₅₀ 605.34±2.62 μg/ml), hydroxyl (IC₅₀ 694.37±2.12 μg/ml) and nitric oxide (IC₅₀ 897.83±1.48 μg/ml) radicals, as well as high reducing power. In Triton WR-1339 induced hyperlipidemic rats, oral treatment with T. asiatica leaves ethyl acetate extract produced a significant (P≤0.005) decrease in the levels of serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), and significant increase in high-density lipoprotein cholesterol (HDL-C) in comparison with hexane and methanol extracts. In high fat diet-fed hyperlipidemic rats, the ethyl acetate extract (200 and 400 mg/kg) significantly altered the plasma and liver lipids levels to near normal.
