Polyphenolic and mineral profiles of berries and leaves of V. myrtillus (bilberry) and V. uliginosum (bog bilberry) collected from northwestern Macedonia were examined in this study. Overall, 70 polyphenolic compounds were identified from various classes. Laricitrin-3-O-pentoside, trans-and cis-piceid, hexahydroxydiphenoyl-galoyl-glucose, and feruloylacetyl glucoside and coumaroyl glucoside of kaempferol were identified for Vaccinium genus. Bilberries had higher total phenolic content than bog bilberry. Major differences in the polyphenolic pattern of berries were found in the flavonols content, whereas leaves differed mostly in the procyanidin content. Berries and leaves of bilberry had higher K and P content compared with bog bilberry and similar contents for Ca, Mg, Mn, and Al, which were comparable to the data for other regions, whereas the measured levels of Zn, Fe, and Cu were higher than the ones reported for bilberries from other regions.
