Indeed, previous studies reported the phytochemicals present in the plant extracts act as reductants in preparing the AgNPs when treated with metal salts.

Antioxidant compounds include flavonoids, phenolic acids, carotenoids, and tocopherols that can inhibit Fe3+/AA induced oxidation, scavenge free radicals, and act as reductants (Ozsoy et al., 2009).
This indicates that CO (and [H.sub.2]) are much better reductants for N[O.sub.x] than the hydrocarbons.
Makarov, Horv<AEa>th, Silaghi-Dumitrescu, and Gao present readers with a comprehensive examination of historical, contemporary, and emerging applications for sulfur-containing reductants. The authors cover synthesis, structure, general properties and analysis, organic reactions, and a great many other related topics.
[12] studied the effect of biomass on the reduction of carbon-bearing pellets using charcoal, bamboo charcoal, and straw as reductant. The results showed that the biomass reductants had little effect on metallisation rate, but certain biomass reductants had a substantial influence on the strength and volumetric shrinkage of the pellets.
Furthermore, the surfactants and reductants on the surface are difficult to remove, which will severely interfere with the SERS results.
However, the molar ratio of [H.sub.2] and [H.sub.2]O to C[O.sub.2] of 0.5: 1: 1 shows the second best performance, which means the moral ratio of total reductants to C[O.sub.2] of 1.5: 1 is optimal.
In the redox reaction, the antioxidants act as reductants and serve as the first-line defense to suppress the formation of free radicals [26].
ORP is related to both the total concentrations of the reductants and the total concentrations of the oxidants in a particular system [11, 12] and offers an overall measurement of redox status in a biological specimen.
