Determination of Antioxidant Activity of Ethanol Extract of Gölevez [(Colocasia esculenta (L.)] Tubers

Abstract

In this study, the antioxidant activity of the ethanolic extract of Colocasia esculenta tubers were determined by four different antioxidant tests including DPPH and ABTS radicals scavenging activities, metal chelating activity and reducing power. The scavenging effect of extract of C. esculenta tubers and standards on DPPH radical at the highest concentration (600 µg mL-1) decreased in the following order: Vitamin C˃Trolox˃C. esculenta˃BHA and were found as 95.4, 93.6, 83.8 and 78.8 %, respectively. The scavenging effect of C. esculenta tuber extract and standards on ABTS radical at the highest concentration (100 µg mL-1) decreased in the order: Trolox = BHA˃C. esculenta and were found as 100, 100, 94.6%, respectively. The metal chelating capacity of extract of C. esculenta tubers and standards decreased in the order of C. esculenta˃BHA˃Trolox at lowest concentration (100 µg mL-1) and was found to be 78.0, 76.0, 63.5 %, respectively. Reducing power of extract of C. esculenta tubers and standards at the highest concentration (600 µg mL-1) followed the order: BHA˃Trolox˃C. esculenta. Total phenolic compound and flavonoid amounts of C. esculenta tubers were designated as 2400 mg GAE/kg extract and 2050 mg QE/kg extract, respectively.
