DPPH is a common abbreviation for the organic chemical compound 2,2-diphenyl-1-picrylhydrazyl. It is a dark-colored crystalline powder composed of stable free radical molecules.

The 2,2-Diphenyl-1-picrylhydrazyl (DPPH) is a popular, quick, easy, and affordable approach for the measurement of antioxidant properties that includes the use of the free radicals used for assessing the potential of substances to serve as hydrogen …

DPPH (2,2-diphenyl-1-picrylhydrazyl) assay The DPPH radical (DPPH) is a stable molecule soluble in methanol characterized by its deep-violet color with an absorption maximum at 515 nm.

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.

The DPPH assay is used to predict antioxidant activities by mechanism in which antioxidants act to inhibit lipid oxidation, so scavenging of DPPH radical and therefore determinate free radical scavenging capacity.

α, α-diphenyl-β-picrylhydrazyl (DPPH) free radical scavenging method offers the first approach for evaluating the antioxidant potential of a compound, an extract or other biological sources.

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.

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].

2023年7月26日 · Of these, the 1,1-diphenyl-2-picrylhydrazil (DPPH) removing assay is the most putative, popular, and commonly used method to determine antioxidant ability. In this review, a general approach to the DPPH radical scavenging assay has been taken.

2021年2月3日 · Since the discovery in 1922 of 2,2-diphenyl-1- (2,4,6-trinitrophenyl) hydrazyl stable free radical (DPPH·), the chemistry of such open-shell compounds has developed continuously, allowing for both theoretical and practical advances in …
