ZnONPs showed superior efficacy, with 47.43%± 0.68 DPPH scavenging and 80%±0.82 ABTS inhibition, as well as robust reducing power in the FRAP assay, comparable to standard ascorbic acid. Antibacterial ...

Antioxidant activity was measured by DPPH radical and ABTS radical scavenging assay using Trolox, ascorbic acid, catechin, and gallic acid as standard antioxidant compounds. The relationship between ...

The highest antioxidant activity for the ABTS assay was recorded when no manure was added. The highest content of total hydroxycinnamic acids was observed when no manure was added, whereas ferulic ...

The scavenging effect of β-sitosterol was also evaluated using the 2,2-azinobis [3-ethylbenzthiazoline]-6-sulfonic acid (ABTS) free radicals scavenging assay (Re et al., 1999; Kamal et al., 2015).

Arbutin, a glucoside of hydroquinone, has shown strong 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation-scavenging activity, especially in reaction stoichiometry. This study ...

In this study, the antioxidant activity of local red wines was determined by four different analytical methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, ...

In vitro anti oxidant activity stem bark extract showed inhibitory concentration 50% (IC50) value of 10.13 than the leaf extract IC50 = 14.85 for DPPH assay. Standard ascorbic acid showed IC50 = 7.28.

Danielle Dimovski (Diva Q) likes “creeper heat” and smokes her ABTs at 225F to 250F for two to three hours using Basques maple hardwood charcoal and cherry wood chunks from SmokinLicious Canada.

Phenolic compounds were quantified in the brown sugar extracts by LC-UV-ESI-MS. Brown sugar aqueous solutions exhibited weak free radical scavenging activity in the DPPH assay and higher antioxidant ...
