Oxidative stress is defined as a condition in which the balance between production of reactive oxygen species (ROS) and antioxidant defense system gets disturbed causes free radical induced diseases. The current research was aimed to carrying out quantification phytochemicals different parts explores activities ethanolic extracts leaf (CFL), seed (CFS), bark (CFB) show their therapeutic importa...

Cornus species fruits are well known as a rich source of antioxidant compounds responsible for their diverse health benefits. The present study aims to investigate the variation of the total antioxidant capacity of Cornelian cherry (Cornus mas L.) fruits during storage, using high-performance thin-layer chromatography (HPTLC) and two spectrophotometric assays based on different mechanisms: the ...

the aim followed in the present study was to evaluate the antioxidant activity of individual vs. combined extracts of rosemary leaves and oak fruit to detect the possible interactions in their antioxidant activity following combination and in order to find a way to use oak fruit natural antioxidants as an available massive source in iran. towards this end, methanolic extracts of rosemary and oa...

the essential oils, isolated by hydrodistillation from the leaves, seeds and rhizomes of heracleum sprengelianum (wight and arnott), collected from the western ghats of peninsula india, were analyzed by gas chromatography (gc) and gas chromatography coupled to mass spectrometry (gc–ms). the antioxidant property of these oils was tested, with and without peroxidation inducer, through the egg yol...

the present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of ervatamia coronaria leaves (apocynaceae) in various systems. dpph radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. the antioxidant activity of methanolic ex...

the aim of present study was to investigate and compare antioxidant properties of green tea and rosemary extracts and determine the effect of their combination on the antioxidant properties. results of total phenols, dpph free radical scavenging assay, total antioxidant capacity, reducing power and their addition into soybean oil, showed that the green tea extract was significantly (p<0.05) mor...

Antioxidant activity of lactic acid bacteria is associated with multiple health-protective effects. Traditional indexes of chemical antioxidant activities poorly reflect the antioxidant effects of these bacteria in vivo. Cellular antioxidant activity (CAA) assay was used in this study to determine the antioxidant activity of cell-free supernatants (CFSs) of 10 Lactobacillus strains. The perform...
