Screening of selected polyphenol compounds in palm oil mill effluent (POME)
Total antioxidant activities and phenolic contents of raw and treated POME extracts (rPOME and tPOME respectively) were investigated. The total antioxidant activity was estimated using DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. The total phenolic contents were measured using Folin-Ciocalteu assay....
