*2.4. Antioxidant Tests*

The antioxidant activity tests were performed by spectrophotometric assays using three di fferent methods: DPPH, ABTS and FRAP (Ferric Reducing Antioxidant Power) test using a 96-well microplate according to Oki et al. [10], Re et al. [28] and Benzie and Strain [29], respectively. In all the assays, Trolox was used as a standard and results are expressed in terms of microgram of Trolox Equivalent Antioxidant Capacity (TEAC) per g of FW of sample.
