Fruit extracts (150 μL) were allowed to react with 2850 μL of the DPPH solution for 24 h in the dark. Then the absorbance was taken at 515 nm. The standard curve was linear between 25 and 800 μM Trolox. Results are expressed in μM TE/g fresh mass. Additional dilution was needed if the DPPH value measured was over the linear range of the standard curve.
