Dolichos biflorus exhibits anti-inflammatory and antioxidant properties in an acute inflammatory model

Abstract

Dolichos biflorus (Muthira) is a branched, suberect, and downing herb, native to most parts of India, and found at altitudes of up to 1000 m, whose seeds can be cooked and eaten. Nutrition plays a key role in building immunity and preventing noncommunicable diseases to a certain extent. The purpose of this study was to evaluate the anti-inflammatory and antioxidant effects of 70% methanolic extract of seeds of D. biflorus (DME) in carrageenan-induced inflammation. DME exhibited maximum percentage of oedema inhibition at a dose of 50 mg/kg at the 3rd hour of carrageenan induction. The effect was higher than that of the standard drug Voveran. The activities of cyclooxygenase, lipoxygenase, nitric oxide synthase, myeloperoxidase, and malondialdehyde showed significant (p < 0.05) reduction whereas the activities of antioxidant enzymes, vitamins C, and reduced glutathione level were increased significantly (p < 0.05) on treatment with DME. Also levels of the acute phase protein, ceruloplasmin, were brought to their normal range in DME-treated rats. Phytochemical analysis showed that the extract contains alkaloids, flavonoids, carbohydrates, proteins, and tannins, which may contribute to its anti-inflammatory and antioxidant activity. Thus the results demonstrate the potential beneficiary effect of DME on carrageenan-induced inflammation in rats. © 2014, Food and Drug Administration, Taiwan. Published by Elsevier Taiwan LLC.
