Abstract
The antioxidant potential of isolated bioactive compounds of Citrus paradisi cv related to seasonal variation, explored in this article. The results revealed significant differences in physical and description of maturity of fruits, regarding to the accumulation of bioactive compounds. It establishes that contents of total phenolic compounds, total antioxidants, total carotenoids, total flavonoids, total pectin proteins as well as taste compounds directly related to maturity stage. The contents of carotenoids, Luteoxanthin, Lycopene, alpha-Carotenoids and beta Carotenoids found to be increased in the December harvested fruits, while non-significant differences were recorded to other harvested periods. The antioxidants potential of these compounds were determined through 2,2-Diphenyl-1-picrylhydrazyl (DPHH), Total Antioxidant Capacity (TAC), Antioxidants index (AI) and Ferric reducing antioxidant power (FRAP) assay method, found to be increased from early to late harvested periods. Pearson correlation coefficient matrix were determined at five different harvesting times followed by determination of the correlation of four essential phytochemicals like Total tannins (TT), Acy and gallic acid with harvesting times. It concluded the proper harvesting time is vital for the effective concentration of bioactive compounds in fruits
