a Values are expressed as the mean ± SD; b different lower case letters within the same row for each infusion tested before and after digestion indicate significant differences according to Duncan’s test at p < 0.05; c expressed as rosmarinic acid equivalents; d expressed as (−)-epicatechin equivalents.
