Catechins and rutin are among the main metabolites found in apple fruit. Sixty apple
genotypes, harvested in 2016 and 2017, were analyzed for their phenolic content and antioxidant
activity. The HPLC analysis showed that the catechin concentration ranged from 109.98 to
5290.47 µg/g, and the rutin concentration ranged from 12.136 to 483.89 µg/g of apple fruit. The level
of DPPH activity ranged from 9.04% to 77.57%, and almost half of the 15 genotypes showed below
30–40% DPPH activity. The apple genotypes ‘Lal Ambri’, ‘Green Sleeves’, and ‘Mallus floribunda’
showed the highest DPPH activity of between 70% and 80%, while ‘Schlomit’, ‘Luxtons Fortune’,
‘Mayaan’, ‘Ananas Retrine’, and ‘Chaubatia ambrose’ showed the lowest ferric reducing antioxidant
power (FRAP) activity (0.02–0.09%). Statistical analysis showed a correlation between DPPH
activity and catechin content (r = 0.7348) and rutin content (r = 0.1442). Regarding antioxidant
activity, fractionated samples of apple genotypes revealed significant activity comparable to that of
ascorbic acid. There was also a consistent trend for FRAP activity among all apple genotypes and
a significant positive correlation between FRAP activity and rutin content (r = 0.244). Thus, this study
reveals a significant variation in antioxidant potential among apple genotypes. This data could be
useful for the development of new apple varieties with added phytochemicals by conventional and
modern breeders.
