As the Senior Program Manager for the Usability Services team at the National Center for Human Factors in Healthcare, Natalie
Abts consults with national and international clients in the medical device industry and leads a team that conducts human factors evaluations for a wide range of medical products.
The antioxidative effect of asparagus was estimated using DPPH,
ABTS and reducing power assays.
The national report has a combination of information and data available at the country level which includes, information on the targets being pursued at the national level; implementation measures taken and assessment of their effectiveness; assessment of progress made towards each national target; description of the national contribution to each of the global
ABTs; description of the national contribution to Global Strategy for Plant Conservation (GSPC); contribution of indigenous peoples and local communities to
ABT,s and updated biodiversity country profiles.

ABTS is well regarded as a peroxidase substrate that generates a metastable radical cation when oxidized.
The determination of TAA was based on the extinction of the absorbance of the radicals DPPH (2.2-difenil-1-picril hidrazil) and
ABTS (2.2-azinobis-3-etilbenzotiazolin-6-sulfonic acid).
Los resultados de los metodos de Folin-Ciocalteau,
ABTS y DPPH, muestran que el extracto de la E.
In this study, It was found that the methanol extract (4.09 mM trolox/mg extract) obtained from maceration method exhibited stronger
ABTS radical cation scavenging activity than ultrasonic bath methanol extract (p>0.05).
Antioxidant activity was determined as [beta]-carotene/linoleic acid (%80.47+-1.83), DPPH (IC50: 0.29+-0.03) and
ABTS (IC50: 47.15+-0.74), ferric reducing antioxidant power (FRAP) (IC50: 18.79+-0.15), total phenolic and total flavonoid contents was found as (4.883+-0.47 mgGAE/g) and (93.322+-1.57 mgQE/g), respectively ,and then 9 different phenolic compounds in ethanol extracts was carried out by HPLC.
The radical cation
ABTS' was produced by reacting 5 mL of
ABTS (Sigma-Aldrich, St.
At the end of the storage period, the oregano 1-to-1 refrigerated samples had the highest values for DPPH,
ABTS and TPC.
