- Abstract
Background Hardy kiwifruit ( Actinidia arguta) is a new species, commercially grown in recent years. Total phenolics ( TPC), vitamin C ( TAA) content, antioxidant activity ( AA) and their year-to-year variability in seven hardy kiwifruit clones were evaluated. TPC was determined using the Folin-Ciocalteu reagent assay. TAA was estimated by determination of l-ascorbic acid and l-dehydroascorbic acid levels using high-performance liquid chromatography. AA was measured using diphenyl-1-picryl-hydrazyl ( DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) ( ABTS) and OH radicals. Results The highest content of vitamin C, in all seasons, was found in D11 (1447-2181 mg kg−1 fresh weight) and phenolics for D11 and M1 clones (2583-3312 and 2228-3414 mg gallic acid equivalents kg−1 fresh weight, respectively). TPC and TAA content showed significant differences between hardy kiwifruit clones and showed significant year-to-year variability. Each year, the level of AA was significantly higher for D11 ( DPPH, ABTS). AA was strongly correlated with TPC and TAA content in Actinidia fruit. Conclusion Hardy kiwifruit are an important source of vitamin C and phenolics, which resulted in their good antioxidant potential. A significantly higher content of these compounds was found in fruit of hybrid origin, which suggests that A. purpurea × A. arguta clones may be useful genetic resources for further interspecific hybridization. © 2012 Society of Chemical Industry
