ANTIOXIDANT ACTIVITY IN FOUR PLUM CULTIVARS

Abstract

Fruit pulp extracts from four plum cultivars (‘Angeleno’, ‘Anna Späth’, ‘Silvia’ and ‘Stanley’) locally grown in Constanța county were analyzed for antioxidant activity by using the DPPH method. ‘Anna Späth’ (88.53 % ) and ‘Silvia’ (82.43 %) had the highest average radical scavenging percentages, while ‘Angeleno’ (63.63 %) had the lowest one. In terms of IC50, this translates to 18.83 mg/mL for ‘Anna Späth’ and 26.19 mg/mL for ‘Angeleno’. Results are comparable to data on other known plum varieties. According to known classifications, all plum extracts can be considered as very strongly antioxidant.
