For ABTS assay, the procedure followed the method of Arnao et al. (2001) with some modifications. The stock solutions included 7.4 mM ABTSradical dot+ solution and 2.6 mM potassium persulfate solution. The working solution was then prepared by mixing the two stock solutions in equal quantities and allowing them to react for 12 h at room temperature in the dark. The solution was then diluted by mixing 1 mL ABTSradical dot+ solution with 60 mL methanol to obtain an absorbance of 1.1±0.02 units at 734 nm using the spectrophotometer. Fresh ABTSradical dot+ solution was prepared for each assay. Fruit extracts (150 μL) were allowed to react with 2850 μL of the ABTSradical dot+ solution for 2 h in a dark condition. Then the absorbance was taken at 734 nm using the spectrophotometer. The standard curve was linear between 25 and 600 μM Trolox. Results are expressed in μM Trolox equivalents (TE)/g fresh mass. Additional dilution was needed if the ABTS value measured was over the linear range of the standard curve.
