Evaluation of oxygen radical absorbance capacity in kampo medicine. [PDF]

open access: yesEvid Based Complement Alternat Med, 2011
Antioxidant capacity of food has come to be shown in terms of oxygen radical absorbance capacity (ORAC) mainly on vegetables or fruit. However, the evaluation of Kampo in terms of ORAC has not yet been accomplished. It is important that such an investigation is also conducted for Kampo medicine.

Modification of the oxygen radical absorbance capacity assay and its application in evaluating the total antioxidative state in fish

open access: yesAdvances in Redox Research, 2022
The oxygen radical absorbance capacity (ORAC) assay is widely accepted as a common method for evaluating the total antioxidative activity in animals and food. The ORAC assay can simultaneously detect both hydrophilic (H-) and lipophilic (L-) antioxidants

Oxygen-radical absorbance capacity assay for antioxidants [PDF]

open access: yesFree Radical Biology and Medicine, 1993
A relatively simple but sensitive and reliable method of quantitating the oxygen-radical absorbing capacity (ORAC) of antioxidants in serum using a few microliter is described. In this assay system, beta-phycoerythrin (beta-PE) is used as an indicator protein, 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) as a peroxyl radical generator, and 6 ...

Determination of antioxidant capacity in some foods by oxygen radical absorbance capacity (ORAC)

open access: yesHeavy metals and arsenic concentrations in water, agricultural soil, and rice in Ngan Son district, Bac Kan province, Vietnam, 2021
Oxygen radical absorbance capacity (ORAC) assay has been applied to determine the Hydrophilic – ORAC index in food. The method measures antioxidant scavenging activity against peroxyl radical induced by 2,2′-azobis(2-amidino-propane) dihydrochloride (AAPH) at 37ºC, used fluororescein as the fluorescent probe.
