Oxygen Radical Absorbance Capacity
ORAC (Oxygen Radical Absorbance Capacity : 活性酸素吸収能力)法は,米国国立老化研究所のCaoおよび米国農務省(USDA)のPriorらにより開発された抗酸化評価法である.生体成分の酸化反応に類似した反応様式を含む評価系として着目されている.米国では,326品目の果実および野菜を中心とした食品の抗酸化能をORAC法により評価し,USDAのホームページで公開すると共に,ORAC法をAssociation of Official Analytical Chemists(AOAC)に提案し,標準法として世界に普及させる方向にある.また,飲料やサプリメントへのORAC値の表記が実際に進んでいる.ORAC法の長所としては,1 ...

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

Oxygen-radical absorbance capacity assay for antioxidants [PDF]
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 ...

Antioxidative Activity of Lactobacilli Measured by Oxygen Radical Absorbance Capacity [PDF]
The reducing ability and antioxidative activity of some species of Lactobacillus were compared under in vitro conditions. Cultures of Lactobacillus delbrueckii ssp. lactis, Lactobacillus delbrueckii ssp. bulgaricus, Lactobacillus acidophilus, and Lactobacillus casei were grown at 37 degrees C in de Man, Rogosa, Sharpe (MRS) broth supplemented with 0.5%

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