Description General description 2,2-diphenyl-1-picrylhydrazyl is a free radical, which shows hydrogen acceptor ability towards antioxidants [1] Hence, it is commonly used in DPPH assay for measuring the antioxidant activity of different natural samples such as wine, fruits [2], herbal tea etc [3]
- DPPH - an overview | ScienceDirect Topics
DPPH is defined as a stable free radical that is commonly used in the DPPH assay to evaluate the antioxidant activity of compounds by measuring the reduction of its purple color to yellow, indicating the ability of substances to neutralize free radicals
- DPPH (2,2-Diphenyl-1-picrylhydrazyl) | Free Radical Scavenger . . .
DPPH (2,2-Diphenyl-1-picrylhydrazyl) is a stable free radical that can be used to measure the radical scavenging activity of antioxidants The odd electron of nitrogen atom in DPPH is reduced by receiving a hydrogen atom from antioxidants to the corresponding hydrazine

However, despite rapid advances in instrumental techniques and analysis, this method has not undergone extreme modification This study presents detailed information about the DPPH method and an in-depth review of different developments
- Antioxidant Assay: The DPPH Method
From the 40+ samples evaluated under this experiment at least ten were found to be potentially powerful antioxidants The plants from which these extracts were obtained should be further analyzed to maximize the possibility of using these in food, drug, and other medical uses
