Abstract

The aims of this research were to estimate the polyphenol content and antioxidant capacity from different parts of cucumber. The antioxidant activity was investigated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP), total flavonoid and phenolic contents were estimated using aluminium chloride and Folin-Ciocalteau reagents assays, respectively. Our finding showed that the ethanolic peel extract contained the highest phenolic (23.08 mg GAE/g) and flavonoids (14.02 mg QE/g). Also, ethanolic peel extract demonstrated significantly (p<0.05) higher FRAP value. Pearson correlation revealed that there were positive correlations (p<0.01) between TPC and TFC with FRAP assay. These findings suggest that consumption of cucumber with peel may provide optimum health benefit than its peeled counterpart.
