Phytochemical and Antioxidant Profile: Cucumber Pulp and Leaves Extracts

BACKGROUND: Many vegetables and fruits have been shown to be sources of antioxidant such as lemons, apples, cabbage, mangoes, beets, guavas AIM: This research aimed determine activity Cucumis sativus L. (cucumber) pulp leaves extracts using DPPH CUPRAC methods, total phenolic content (TPC), flavonoid (TFC), correlation TPC TFC on activity, between the two identification marker, marker content. METHODS: Antioxidant was examined by determining IC50 AAI EC50 CUPRAC. measured UV-visible spectrophotometer. Correlation analysed Pearson’s method. RESULTS: cucumber in range 0.22 - 2.18, whereas 0.07 0.95. All showed activity. Ethyl acetate extract had highest assay, n-hexane assay. value (21.47 g QE/100 g) (2.34 GAE/100 g). Flavonoids contributed method compounds gave a contribution Quercetin ethanol 0.00114%. positive but not significant. CONCLUSION: methods were linear.
