Effects of Some Extraction Solvents on the Antioxidant Properties of Strawberry Fruit

Abstract

In this paper, antioxidant activity of strawberries extracted with different solvents was investigated since they are consumed by people due to their anticancer, anti-atherosclerotic, anti-inflammatory and anti-neurodegenerative properties. For this purpose, different acidified extraction solvents such as water (ES1), acetone (ES2), acetonitrile (ES3), methanol (ES4) and ethanol (ES5) were used in extraction process of strawberries. The effects of different extraction solvents on the antioxidant activity were evaluated by measuring the reducing power, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, total flavonoid content (TFC) and total phenolic content (TPC). Experimental results indicated that the obtained data varied with different extraction solvents. All antioxidant activity assay results showed that the highest results were obtained with acetone extracts.
