  3. Fresh and dried fig samples homogenized in methanol and 60% acetone adapted from Brand-Williams et al., 1995

  4. Supernatants were aspirated. Homogenates were centrifuged.

  5. Antioxidants react with free radicals ΔAbs 515 nm

  6. Samples were compared with Trolox (water-soluble vitamin E analogue) in each solvent Trolox Standard Curve
