Antioxidant potential of solvent extracts of Kappaphycus alvarezii (Doty) Doty – An edible seaweed
TLDR
In this paper, various solvent extracts of Kappaphycus alvarezii, an edible red seaweed (family Solieriaceae), were screened for total phenol content and antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferrous ion chelating activity, reducing power and reducing activity assays in a linoleic acid system with ferrothiocyanate reagent (FTC).About:

Antioxidant activities and total phenolic contents of various extracts from defatted wheat germ
TL;DR: In this paper, the antioxidant properties of DWG extracts were measured using various in vitro assays using aqueous DWG extract, and the results showed that the 70% ethanol extract showed the best DPPH radical scavenging power while the 100% ethanol extraction showed the highest ABTS radical scavengence activity and reducing power.

Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.
