Table 2.
Total phenolic (TPC), flavonoid (TFC) and anthocyanin contents (TAC) and DPPH scavenging activity of groups of wild cranberry clones collected from four Canadian provinces: Newfoundland and Labrador (NL), Nova Scotia (NS), New Brunswick (NB) and Prince Edward Island (PE), and cultivars (CV) Franklin and Bergman. GAE = gallic acid equivalents, CE = catechin equivalents, C3GE = cyanidin-3-glucoside equivalents, fw = fresh fruit weight.
