evaluation of antioxidant activity using an improved dmpd,the free radical scavenging activity as antioxidant of the monoterpenes was evaluated using the stable radical n,n-dimethyl-1,4-phenylenediamine (dmpd) with concentrated 100 mm dmpd solution
- How does DMPD + affect antioxidant capacity?
- In this level of concentrations, the antioxidant Trolox is able to transfer a hydrogen atom to the radical cation DMPD Å+ , so the colour of the solution of the radical diminishes proportionally to its concentration (Asghar et al., 2007). These results confirm the capacity of the radical cation DMPD Å+ to evaluate the antioxidant capacity. ... ...
- 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.
- Does DMPD scavenge free radicals?
- The free radical scavenging activity as antioxidant of the monoterpenes was evaluated using the stable radical N,N-dimethyl-1,4-phenylenediamine (DMPD) with concentrated 100 mM DMPD solution (Asghar et al. 2007; Badawy et al. 2016;Fogliano et al. 1999). Standard solution of ascorbic acid (50-1000 mM) was prepared in deionized water. ... ...
- How do you make DMPD free oxidant?
- Briefly, the DMPD (Sigma-Aldrich) free oxidant was generated by adding 0.1 ml of DMPD aqueous solution (100 mM) to 0.05 ml of aqueous potassium persulfate (0.4 mM), and the final volume was made to 10 ml with sodium acetate buffer (pH 5.6). ... ... The results were represented in μg of ascorbic acid equivalent (AAE)/ ml of plant extract.
