Variation in Phytochemical Composition of Blueberry Cultivars and Breeding Selections

Polyphenolic composition and antioxidant activity of the under-utilisedPrunus mahalebL. fruit

“…The anthocyanin contents of P. mahaleb did not notably differ between the two growth conditions, as well as the year of picking, with the exception of 2012 (Nursery 1) which was not a favourable growing year, as demonstrated by the low yield (data not reported) and low anthocyanin ‘productivity’ (Table ). This finding has been attributed to growing seasons and environmental factors . A similar finding has been reported for anthocyanin content in raspberries .…”

“…This finding has been attributed to growing seasons and environmental factors. 29 A similar finding has been reported for anthocyanin content in raspberries. 30 Total anthocyanin content in samples analysed over two years did not show significant differences in Ceylon gooseberry.…”

Anthocyanin composition and content of blueberries from around the world

“…Blueberries (Fig. 1) contain a wider range of anthocyanidins than most types of berries, with malvidin predominating and similar concentrations of delphinidin, cyanidin, petunidin and pelargonidin [11][12][13][14][15]. The glycosidic forms found in blueberries are glucosides, galactosides and arabinosides, with all possible permutations being found in at least some cultivars, although relative proportions vary widely and in some cultivars may be absent altogether.…”

“…Blueberries contain a significant proportion of acylated anthocyanins, primarily the p-coumaroyl and acetyl esters on C-6 of the various sugar residues [16,17]. The proportion of acylated species is highly variable among different cultivars, with some having barely detectable amounts [11,12,14,18].…”

Anthocyanins and other polyphenolics in American elderberry (Sambucus canadensis) and European elderberry (S. nigra) cultivars

“…Research papers describing the anthocyanin composition of different S. canadensis cultivars appear to be nonexistent. Numerous factors influence the phenolic content of any fruit or fruit product, including: species, cultivar, ripeness, growing season, yield, field management practices, environmental factors, post‐harvest storage, and processing factors 7, 12, 27–30. The objective of this study was to compare overall chemical composition, and the anthocyanin and other polyphenolic profiles of eight different genotypes of S. canadensis (‘Adams 1’, Adams 2', 'Johns, ‘Scotia’, ‘York’, ‘Gordon B’, ‘Netzer’, and ‘Harris 2’) with two different genotypes of S. nigra (‘Korsør’ and ‘Haschberg’).…”
