Title of the Study: Gamma-oryzanol rich fraction regulates the expression of antioxidant and oxidative stress related genes in stressed rat’s liver / Maznah Ismail, Ghanya Al-Naqeeb, Wan Abd Aziz bin Mamat, Zalinah Ahmad, /Nutrition & Metabolism
From the findings of this study it was concluded that Gamma-oryzanol rich fraction showed potential antioxidant activity greater than OR in the regulation of antioxidants and oxidative stress gene markers.
Year of Study: 2005
Title of the Study: Antioxidant activity of gamma-oryzanol: mechanism of action and its effect on oxidative stability of pharmaceutical oils / Claudia Juliano Massimo Cossu Maria Cristina Alamanni Luisella Piu / International Journal of Pharmaceutics
The results of this study demonstrate that gamma-oryzanol is an organic radical scavenger able to prevent AMVN- triggered lipoperoxidation.
Year of Study: 2003
Title of the Study: Potential functionality and digestibility of oryzanol as determined using in vitro cell culture models / Chih-chun Jean Huang / LSU Doctoral Dissertations
The results of this study showed that, in some situations, γ-oryzanol could present a more effective antioxidant activity than α-tocopherol, in terms of reducing tert-butyl hydroperoxide promoted oxidative damage on cellular mitochondrial activity.
Year of Study: 2001
Title of the Study: Antioxidant activity of tocopherols, tocotrienols, and gamma-oryzanol components from rice bran against cholesterol oxidation accelerated by 2,2'-azobis(2- methylpropionamidine) dihydrochloride / Z Xu, N Hua, J S Godber /Journal of Agricultural and Food Chemistry
The results of this study demonstrated that Gamma Oryzanol components had higher antioxidant activity than that of any of the four vitamin E components.
Year of Study: 2001
Title of the Study: Antioxidant activities of major components of γ-oryzanol from rice bran using a linoleic acid model /Zhimin Xu and J. Samuel Godber / Journal of the American Oil Chemists' Society
In this study, major components of Gamma Oryzanol demonstrated significant antioxidant activity.
Year of Study: 1991
Title of the Study: Preventive effect of antioxidants on lipid peroxidation in the retina / T Hiramitsu, D Armstrong / Ophthalmic Research
This study indicated that Gamma Oryzanol was more than four times as effective at stopping tissue oxidation as vitamin E.
