The ethyl acetate and n-butanol fractions displayed clearly a stronger quenching activity (over 80%) against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO) radicals, whereas all of them were observed with a lower activity (below 22%) against N,N-dimethyl-p-phenylendiamine (DMPD) radical.
This method uses the stable free 2,2-diphenyl-1-picrylhydrazyl (DPPH) to estimate the activity of antioxidant.
pumila was first analyzed for their antioxidant activities using 2,2-diphenyl-1-picrylhydrazyl.

La capacidad antioxidante de las distintas muestras se evaluo como la capacidad de atrapar radicales utilizando la tecnica del radical libre 2,2-Diphenyl-1-picrylhydrazyl (DPPH), siguiendo la metodologia propuesta por Brand-Williams et al.
The antioxidative capability of the compounds under study has been evaluated by using different assays like a ferric reducing/antioxidant power assay (FRAP), an oxygen radical adsorption capacity method (ORAC), colourization assays using stable coloured free radicals, such as 2,2-diphenyl-1-picrylhydrazyl (DPPH), a 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical cation or a reactive oxygen species, due to their intensive absorbance in the visible region [2, 35-38].
Known methods include the active oxygen method (AOM) and its automated versions (Rancimat and SAFFEST) for lipophilic phases, and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) or oxygen radical absorption capacity (ORAC) for aqueous environments.
