Different lowercase letters for the same phenolic fraction indicate significant differences (p < 0.05) among treatments. ARSA, ABTS radical scavenging activity; DRSA, DPPH radical scavenging activity; HRSA, hydroxyl radical scavenging activity; MCA, metal chelation activity; TE, Trolox equivalents; EDTAE, ethylenediaminetetraacetic acid equivalents.
