They showed considerable free-radical-scavenging properties in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay with the RC (50) values of 9.
Among these are the methods that use azo-compounds to generate peroxyl radicals, such as the "TRAP" method (Total Radical-Trapping Antioxidant Parameter) and ORAC; the scavenging of radical cation by 2,2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) such as the ABTS or "TEAC" method (Trolox Equivalent Antioxidant Capacity); the scavenging of stable radical by 2,2-diphenyl-1-picrylhydrazyl known as the DPPH method and the scavenging of radical cation by N,N-dimethyl p-phenylenediamine for the DMPD method.
To do so, the researchers used a olorimetric Folin-Ciocalteu assay and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) or 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, respectively.
