Comparing the TPC results for different extraction methods presented
in Table 2 (assays groups 1 and 2) we observe that the
best relation between % AA and TPC was obtained by the SFECO2/
EtOH, with higher TPC (131±5mg GA/100 g seeds) and TEAC
of 130±3mmolTrolox/100 g seeds and%AAof 63±5. For the Soxhlet
extraction, the solvent EtOH result in higher TPC and antioxidant
activity (172±6mg GA, 224±10mmol Trolox/100 g seeds and
44±6% AA), due to the large solvent polarity, compared with EtAc.
Comparing SFE and SE, the phenolic fraction by SE-EtOH presented
higher TPC and % AA by DPPH method (TEAC), while % AA by -
carotene bleaching was lower than for SFE with CO2/EtOH.
