The hydrophilic fraction contributed 96.4% and the lipophilic
fraction 3.6% to the total ORAC (sum of ORAC-L and ORAC-H
values). The high values of ORAC-H are possibly due to the
phenolic compounds that display high antioxidant activity, which
has been similarly reported for the Bush tomato previously (2.0% for
the ORAC value of lipophilic fraction and 98% for the hydrophilic
fraction).34 This result suggests that phenolic compounds are the
major contributor to the antioxidant activity of purple tomato.
