background: nowadays, there's a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants. therefore, introduction of new natural antioxidants (especially those with plant origin) is very important. objective: the present study explores the chemical constitution and antioxidant activity of leaf extract of hyssopus officinalis l. and extract of aerial ...

Glutathione peroxidase (GPx), peroxiredoxin (Prx), and catalase are the major antioxidants at the cellular level and protect cell compartments against hydrogen peroxide (H2O2). In addition, they affect cellular processes such as cell signaling by modulating H2O2. In this paper we demonstrate that there is a synergetic coupling between GPxs, Prxs themselves and also with other antioxidants when ...

background: oxidation of lipids causes reduction of different properties of products that contains lipids. nowadays, there is a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants such as bha, bht and tbhq. objective: in this study, extract of aerial parts of echinacea purpurea l. was used instead of synthetic antioxidants in cake then, antioxidant a...

Natural antioxidants compounds are present in leaf, rhizome, stem, fruits, vegetables, tea etc. They are recognized as important compounds in conferring stability against oxidation in vitro. Natural antioxidant compounds can be classified into Exogenous antioxidants and Endogenous antioxidants, Enzymatic and NonEnzymatic antioxidants. Naturally occurring antioxidants compounds are carotenoids, ...

antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. a variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. in this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...

Germination is one of the most effective processes to improve the quality of legumes. Vitamins and some other compounds that might be considered beneficial as antioxidants, often change dramatically during the course of germination. Antioxidants might be defined as compounds which are capable of preventing, delaying or retarding the development of rancidity or other flavor deterioration in food...
