WebFeb 25, 2011 · DPPH assay This method was developed by Blois (1958) with the viewpoint to determine the antioxidant activity in a like manner by using a stable free radical α, α-diphenyl-β-picrylhydrazyl (DPPH; C18H12N5O6, M = 394.33). The assay is based on the measurement of the scavenging capacity of antioxidants towards it. WebDPPH assay at different concentrations (0.5, 1.0, 1.5, 2.0 and 2.5mg/ml). The higher percentage inhibition of scavenging activity of the plant extract for DPPH showed 63.15±0.86% in 2.5mg/ml
Web2.4.2. DPPH Assay Antioxidant activity was quantified with DPPH following the procedure explained before. In this case, the number of worms was the same in each condition, so aliquots of 150 µL of each filtered worm solution were added to a 96-well plate and made react with 150 µL of DPPH 0.04 mg/mL. WebAbstract Background: 2,2-Diphenyl-1-picryl-hydrazyl (DPPH) radical decomposition in alcohol solution is widely used, characterizing plant antioxidants that can rise in serum after fruit and vegetable intake. However, this test failed reproducible results with serum due to protein precipitation.
