Abstract

In this study, bioactive compounds and antioxidant capacity of pulp taken from three CITRUS cultivars (‘Sanguinello’, ‘Tarocco’ and ‘Page’) were investigated during ripening to determine suitable harvesting time. Some parameters were measured such as TSS, TA, TSS/TA, total CAROTENOID, total phenolics, total FLAVONOID, total anthocyanin, ASCORBIC ACID content and antioxidant capacity based on DPPH.+ and ABTS.+ radicals scavenging. Results showed that no significant differences were observed for TSS and TA in all cultivars and the last three harvesting dates. Total CAROTENOID level increased during ripening. The total content of phenolic was superior in September sampling date taken from ‘Sanguinello’ and ‘Tarocco’. Total FLAVONOID and anthocyanin increased but ASCORBIC ACID levels decreased during ripening. Antiradical efficiency (AE) increased in ‘Tarocco’ and ‘Page’ fruits in September. Although AE elevated in ‘Sanguinello’ in November, but no significant differences observed between samples taken from November to December. According to antioxidant assay, antioxidant capacities at all cultivars were in highest level at early of December. In general, due to optimum fruit quality and antioxidant capacity during late November and early December, we suggest that these times are suitable for harvesting of studied cultivars.
