AbstractAntioxidant activity, urinary tract protective activity, and cardioprotective anti-platelet effects are among the bioactivities associated with dietary phenolics. These bioactivities were measured in vitro in fruit extracts from seven Vaccinium species and five non-Vaccinium species to determine their relationship to total phenolic content and to anthocyanin and proanthocyanidin content. Berries belonging to the genus Vaccinium were particularly high in antioxidant activity and urinary tract protective anti-adhesion activity, while anti-platelet activity varied among species. There was a positive relationship between antioxidant activity (using the oxygen radical absorbing capacity (ORAC) assay) and both the total phenolic (R2 = 0.76) and anthocyanin content (R2 = 0.43) of the fruit, although there was no relationship between ORAC and proanthocyanidin content. There were no relationships between anti-adhesion activity and total phenolic content, anthocyanin content, or proanthocyanidin content. Likewise, no relationships were observed between anti-platelet activity and total phenolic content, anthocyanin content, or proanthocyanidin content. These results suggest that while antioxidant properties are characteristic of all fruit phenolics, in vitro anti-adhesion and anti-platelet bioactivities may be due to less abundant phenolic subgroups.
