Abstract
The effect of fenugreek seeds (Trigonella foenum graecum) on blood lipid peroxidation and antioxidant status in alloxan diabetic rats was studied. Increased lipid peroxidation and alterations in circulating antioxidants were observed in the diabetic state. The levels of glutathione, ascorbic acid and β‐carotene in blood were significantly lowered and α‐tocopherol content was increased. Supplementation of fenugreek seeds in the diet lowered lipid peroxidation. The contents of glutathione and β‐carotene were increased and the α‐tocopherol content was lowered. The level of ascorbic acid was unaltered. The level of antioxidants were higher in normal rats which were fed with the fenugreek supplemented diet compared with control animals which were fed commercial rat chow. The study shows that disrupted free radical metabolism in diabetic animals may be normalized by fenugreek seed supplementation in the diet.­Copyright © 1999 John Wiley & Sons, Ltd.
