Optimization of Extraction Solvent and Fast Blue BB Assay for Comparative Analysis of Antioxidant Phenolics from Cucumis melo L.

ABSTRACT: Melon (Cucumis melo L.) fruits contain multiple health-promoting compounds, including phenolic compounds, which are antioxidants. Accurate measurement of antioxidant activities and total phenolic contents (TPCs) require an efficient solvent extraction. In this study, we evaluated free radical scavenging activity and TPC of melon extracts extracted with 22 different solvent combinations. The DPPH scavenging activities were high in 100% methanolic (39.48 ± 0.36 µg g-1) and 80% methanolic extracts (38.99 ± 0.44 µg g-1). Similarly, the ABTS scavenging activities were high in 100% methanolic (315.11 ± 10.38 µg g-1) and 80% methanol extracts (297.39 ± 14.98 µg g-1). The Folin-Ciocalteu (F-C) assay is typically used to measure TPC but may be affected by interference from sugars and other compound
