Antioxidant compounds such as flavonoid substances are essential for maintaining optimum cellular work. Phenol and flavonoid compounds are widely contained in plants, included in strawberry. The purposes of this research were to compare antioxidant profiles from different organs of strawberry using two antioxidant testing methods 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Cupric reducing antioxidant capacities (CUPRAC) and also its phytochemical content. Materials and Methods: Antioxidant activities, total phenolic content (TPC) and total flavonoid content (TFC) were conducted by UV-Vis spectrophotometry. Correlation of TPC and TFC with their IC50 of DPPH and EC50 CUPRAC were analyzed by Pearsons method. Results: All different organs extracts of strawberry exposed IC50 of DPPH varied from 0.22-10.14 μg mL1 and EC50 of CUPRAC from 130.42-250.14 μg mL1. Ethanol stem extract gave the highest TPC 18.62 g gallic acid equivalent (GAE) 100 g1, while ethyl acetate leaves extract showed the highest TFC 7.40 g quercetin equivalent (QE) 100 g1. The TPC in fruit and leaves extract were significantly negative correlation with their IC50 DPPH (r = -0.865; r = -0.970, p<0.01). Conclusion: All different organs extracts of strawberry were very strong antioxidant by DPPH method. Waste products of strawberry (leaves and stem) had antioxidant potential. The major contributor in antioxidant activities of fruit and leaves extracts by DPPH assay were phenolic compounds. Only strawberry fruits extract showed linear results in DPPH and CUPRAC assays.]]>Carocho, M. and I.C.F.R. Ferreira,2013511525Chen, F., F. Li, L. Lu, X. Zhang, X. Xu and D.
