n,n -dimethyl- p -phenylenediamine dihydrochloride-based,we have modified the original method of measuring antioxidant content by dmpd by using plasma as an oxidant (free radical generator) itself and producing a pink color with dmpd that can be measured at 505 nm. in this article, we report the oxidant effect of plasma during human aging.
fully automated spectrometric protocols for determination of
the study resulted in the optimization, automation and precise description of protocols of six photometric methods, namely the dpph, teac, frap, dmpd, free radicals kit and blue cro 5 assays, which cand be used for the determination of antioxidant activity.
n,n-dimethyl-p-phenylenediamine cas-number 99-98-9 chemodex,n,n-dimethyl-p-phenylenediamine (dmpd) is a redox/oxidative stress indicator. it readily forms stable radical cations, involved in a variety of redox reactions. has also been used to quantify labile sulfide in proteins, to detect sterolhydroperoxides, and for the measure of the antioxidant activity and used as an intermediate to produce dyes.
short overview of some assays for the measurement of
some of the most common antioxidant assays based on scavenging activity include orac, dpph, 2,2′-azinobis-(3-ethylbenzothiazole-6-sulphonate) (abts)/teac assay and n,n-dimethyl-p-phenylenediamine radical scavenging (dmpd) assay [31,32].
technical data sheet (tds) with high quality,it is the efficient antioxidant used in tire industry and widely used for rubber products. it can completely avoid the tire surface to become red due to the use of antioxidant 6ppd and ippd. application: it is can be used for load tires, cross-country tires and various tires and bias-ply tires.
polyphenol contents and in vitro antioxidant activities of
in this study, we investigated the ferric ion (fe 3+) reducing power (frap) and cupric ion (cu 2+) reducing power (cuprac method) as well as the dpph∙ scavenging, abts + scavenging, dmpd + scavenging, o 2− scavenging and ferrous ion (fe 2+) chelating activities of lek.

- Can DMPD be used to measure antioxidant activity?
- A novel method for measuring the antioxidant activity using N, N-dimethyl-p-phenylenediamine (DMPD) was developed. The radical cation of this compound gives a stable colored solution and a linear inhibition of color formation can be observed in the presence of 0. 2-11 microg of TROLOX. The experimen …
- Does DMPD work on real foods?
- The effectiveness of the DMPD method on real foods was verified by evaluating the antioxidant ability of wine samples coming from different areas of Campania, Italy. Antioxidant capacity of wines is strictly related to the amount of phenolic compounds.
- How does DMPD decolorize a food sample?
- An improved decolorization method for measuring the antioxidant activity of food samples using N,N-dimethyl-p-phenylenediamine (DMPD) is developed. DMPD radical cation (DMPD •+) is generated through a reaction between DMPD and potassium persulfate and is subsequently reduced in the presence of hydrogen-donating antioxidants.
- What is DMPD chemistry?
- The chemistry involves the generation of a more stable DMPD radical mono-cation by a reaction with potassium persulfate. The DMPD radical cation generator does not involve Fe (II) ions, which through Fenton's Reaction could cause negative deviation in the antioxidant activity of food extracts.
