DPPH Assay:

Article Title: Red Macroalgae as Sources of Antioxidant and Multifunctional Ingredients for Functional Foods: A Biorefinery Approach
Article Snippet: .. The DPPH assay uses a stable radical (2,2-diphenyl-1-picrylhydrazyl, Thermo Fisher Scientific, Waltham, MA, USA) to assess the antioxidant capacity of extracts [ , ]. ..

Article Title: Development of chalcones structure-related to avobenzone: Photoprotection, photostability, and safety evaluation.
Article Snippet: .. In vitro free radical scavenging evaluation The antioxidant potential was evaluated using 2,2′- azi nobis- (3- ethylbenzothiazoline- 6- sulfonic acid) (ABTS) and 1,1- diphenyl- 2- picrylhydrazyl (DPPH) assays.39,40 Chalcone samples (2.5, 5, 10, 25, and 50 μg/mL) were incubated with ABTS or DPPH solutions for 30 min under light- protected conditions, and absorbance was measured using a multimode microplate reader (Thermo Scientific Varioskan Flash) at 734 nm for the ABTS assay and 517 nm for the DPPH assay. ..
