The
seasonal changes in the some biochemical substances in fruits of ten
persimmon cultivars (PCNA cultivars such as ‘O'Gosho’, ‘Fuyu’, ‘Hana
Fuyu’ and ‘Jiro’, and non-PCNA cultivars such as
‘Vainiglia’, ‘Hachiya’, ‘Kaki Tipo’, ‘Eylül’, ‘Amankaki’ and
‘Harbiye’) were determined in Dörtyol-Hatay (Turkey) in the 12th and 13th year after planting (YAP). All results were expressed on a fresh weight
basis. The fructose and glucose were the predominant soluble sugar in different
persimmon cultivars, and the amounts of fructose and glucose in persimmon
fruits showed an apparent increase during fruit development. The total
phenolics (TP), total flavonoids (TF) and soluble tannins (ST) concentration in
fruits showed a continuous decrease from July to consumption maturity. The TP,
TF and ST amounts of non-PCNA group fruits in tree
maturity were higher more about 3.6, 4.9 and 5.6 fold than
those of the PCNA group fruits, respectively. In consumption
maturity, the
highest TP content of non-PCNA group fruits was found in ‘Eylül’ (131.3 mg/100 g) and ‘Hachiya’ (128.5 mg/100 g) cultivars. The fruits of non-PCNA cultivars had 2.3 and 1.9
fold more total antioxidant capacity (TAC) than those of PCNA cultivars
according to FRAP and TEAC, respectively. In addition, the results indicated that a good correlation
between the TP content and TAC of persimmon cultivars (r = 0.98, at p
<0.05).
