Antioxidant Activity of Phytosterols, Oryzanol, and other Phytosterol Conjugates
Antioxidant activity of phytosterols, oryzanol, ferulic acid ester of sterols, corn fiber oil, and rice bran oil was investigated. Commercial soybean oil and distilled soybean oil FAME were used as substrates for both oxidative stability determination and viscosity analysis after the oil was oxidized. At low concentration, these materials did not improve the oxidative stability of the oil subst...

Antioxidant Activity of γ-Oryzanol: A Complex Network of Interactions
γ-oryzanol (Orz), a steryl ferulate extracted from rice bran layer, exerts a wide spectrum of biological activities. In addition to its antioxidant activity, Orz is often associated with cholesterol-lowering, anti-inflammatory, anti-cancer and anti-diabetic effects. In recent years, the usefulness of Orz has been studied for the treatment of metabolic diseases, as it acts to ameliorate insulin ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Effect of Different Solvents on Phytosterols and Antioxidant Activity of Cocoa Beans
Cocoa beans are rich in a number of beneficial bioactive compounds that are good for health. However, they have not been exploited to their fullest to produce high quality extract containing stable bioactive compound. The main objective of this study was to determine the effectiveness of the different solvent used for extraction on yield of cocoa butter extracts, oxidative value, phytosterols c...
