Antioxidant Effect of Triticum Aestivium (Wheat Grass) in High-Fat Diet-Induced Oxidative Stress in Rabbits

Methods Find Exp Clin Pharmacol. 2010 May;32(4):233-5. doi: 10.1358/mf.2010.32.4.1423889.

Abstract

Wheat grass is used as a general health tonic and is reported to be effective against several medical disorders, although detailed literature is not available. Besides drug therapy, a number of medicinal plants are effective in treating hyperlipidemia. This study examined the effects of wheat grass on high-fat diet-induced hyperlipidemia in rabbits. Thirty rabbits were divided into 3 groups of 10 rabbits each, group I receiving a control diet, group II a high-fat diet and group III a high-fat diet together with wheat grass over a period of 10 weeks. Fasting serum samples from the animals were analyzed for total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), malondialdehyde (MDA), reduced glutathione (GSH) and vitamin C, and the results were compared. The high-fat diet resulted in hyperlipidemia and an increase in oxidative stress, indicated by a significant rise in MDA levels, whereas antioxidant levels of GSH and vitamin C were significantly reduced. Wheat grass supplementation with a high-fat diet resulted in improved lipid levels (decreased total cholesterol and increased HDL-C) together with significantly reduced MDA levels and increased GSH and vitamin C levels. These results indicate the beneficial role of wheat grass in ameliorating hyperlipidemia and the associated oxidative stress.
