INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES Screening of antioxidant potentials in Dioscorea bulbifera

Abstract

Abstract Dioscorea bulbifera is a majo r staple food crop which is a species of yam widely distributed around the world in tropical and subtropical reg ions. Dioscorea bulbifera have been traditionally used to lower glycemic index, thus providing a more sustained form of energy and better protection against obesity and diabetes. It also has anti-cancer properties. The present study was undertaken to investigate the antioxidant activity of Dioscorea bulbifera. The ethanolic extracts of tuber Dioscorea bulbifera were screened for their en zy matic and nonenzymatic antio xidant activity. The level of enzymat ic antioxidant namely Glutathione peroxidase (GPx), Catalase (CAT), Supero xide dismutase (SOD), Glucose-6-phosphate dehydrogenase (G6PD) and glucose-s-transferase (GST) was found to be very impressive. Dioscorea bulbifera contains good and commendable store of non enzymat ic antio xidants namely reduced glutathione (GSH), Vitamin -C and Vitamin -E. Ou r results have good significance, as this increase the innate antioxidant potential of Dioscorea bulbifera, which is useful in provid ing the antio xidants needs in the diet and thereby Dioscorea bulbifera accomplishes high value nutritive and natural store of antioxidant
