Moreover, the scavenging activity of the extracts was measured using DPPH, hydrogen peroxide, and reducing power.
Temperature, pH, and E/S ratio were selected as the independent variables and analyzed according to the preliminary experiment results, whereas DPPH free radical scavenging activity was selected as the dependent variable.
In the antiradical scavenging property test the extract showed at 64.1 ug/ml 50% DPPH radical scavenging activity and in the MTT assay the extract has relatively low cytotoxicity where the IC50 value of extract against Vero cells was 1078.69 ug/ml.
Antioxidant activity of ethyl haematommate, ethyl orsellinate, and brialmontin 1 is not reported, whereas zeorin has not shown potent antioxidant activities in DPPH, SOI, NO, and metal chelating assays [18].
The antioxidant assays chosen for this study are 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azino-bis-(3- ethylbenzothiazoline-6-sulfonic acid) (ABTS), and ferric ion reducing antioxidant power (FRAP) assays which were used to measure the relative antioxidant ability to scavenge the free radicals produced in the reagents.
The concentration of Zn, Fe and total antioxidant capacity determined by DPPH method declined with longer polishing, while FRAP method was not detected the capacity after 15 s polishing.
DPPH and KBr were attained from Aldrich Chemical Co.
where; [A.sub.0], [A.sub.1] and [A.sub.2] are absorbance of DPPH without sample, sample and DPPH, and sample without DPPH, respectively.
The antioxidant activity of ethanolic extract of sugar beet powder and cookies was determined based on the radical scavenging ability in reacting with a stable DPPH free radical (Mohdaly et al.,2010; Sakac et al., 2010).
