Antioxidative Activity of Tocotrienols

Antioxidative Activity of Sixty Plants from Iran

Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. This article describes a test method for screening the antioxidant activity of 60 Iranian plant...

Dose-dependent cholesterolemic activity of tocotrienols.

Tocotrienols and tocopherols are isoforms of vitamin E. Vitamin E may exhibit antioxidant, prooxidant and non-antioxidant activities depending upon circumstances. In this study, the effect of tocotrienols and a-tocopherol on the activities of HMG CoA reductase and cholesterol 7 a-hydroxylase was investigated. Pure tocotrienols were isolated from palm fatty acid distillate and pure a-tocopherol ...

Antioxidative Activity of Melia Azedarach Linn Leaf Extract

The antioxidant activity of the melia azedarach was investigated in rats with ethanol-induced erythrocyte damage. Chronic administration of ethanol (20% w/v, 2 g/kg.p.o.,daily for four weeks) increased the level of lipid peroxidation (LPO), decreased the activity of superoxide dismutase (SOD) and catalase and reduced the content of glutathione (GSH). The concurrent treatment of ethanol-admini...
