Abstract

Bound phenolics from oat grain endosperm–germ and bran fractions contributed to 73.30%–82.22% of total phenol content and 59.33%–66.83%, 67.86%–75.74%, and 59.02%–67.86% of total antioxidant capacity in ABTS-AC, DDPH-AC, and FRAP-AC, respectively. Bound phenolics form the bulk of the total phenol content and antioxidant capacity, especially in bran fraction.
