The Concentrations of Tocols and ^|^gamma;-Oryzanol Compounds in Rice Bran Oil Obtained by Fractional Extraction with Supercritical Carbon Dioxide

Determination of gamma oryzanol in rice bran oil by HPLC with molecularly imprinted solid-phase extraction

A molecularly imprinting technique can be used for the separation of gamma oryzanol which gives high selectivity and affinity towards template molecules. This technique was successfully applied for the molecularly imprinted polymer (MIP) synthesis via photopolymerization method by using diethylaminoethyl methacrylate (DMAEMA) as a function monomer, gamma oryzanol as template, dodecanol as porog...

Gamma-oryzanol from rice bran oil – A review

Rice bran oil is unique among edible oil due to its rich source of commercially and nutritionally important phytoceuticals such as, oryzanol, lecithin, tocopherols, and tocotrinols. However, most of these phytoceuticals are removed from the rice bran oil as waste byproducts during the refining process. γ-oryzanol is one of such component having the potential to be used in nutraceutical, pharmac...

Genotoxicity of rice bran oil extracted by supercritical CO2 extraction.

Rice bran oil extracted by supercritical CO2 extraction (RB-SCE) reportedly exhibits pharmacological activities such as antioxidant and in vivo hair growth-inducing effects. Such activities raise the possibility of the development of novel hair growth-inducing agents using RB-SCE. The aim of this study was to investigate the potential genotoxic effects of RB-SCE in three short-term mutagenicity...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Degradation kinetics of gamma-oryzanol in antioxidant-stripped rice bran oil during thermal oxidation.

Gamma-oryzanol, a group of phytosterol ferulates found in rice bran, possesses antioxidative activity and other bioactivities. The kinetics of thermal degradation of gamma-oryzanol in stripped rice bran oil (SRBO) were investigated under heating at 132, 160, 192 and 222 degrees C for 480, 140, 60 and 50 h, respectively. Losses of the overall gamma-oryzanol and its components (cycloartenyl ferul...
