Background: Nowadays, natural antioxidants are used to replace synthetic antioxidants for delaying or preventing the oxidation of edible oils. In this study, phenolic compounds and antioxidant properties of methanol extracts of Spirulina microalgae (Arthrospira platensis) were measured. Methods: Phenolic content was measured by Folin–Ciocalteau method and antioxidant activity was measured by th...

Nowadays, consumers are demanding more natural foods, obliging the industry to include natural antioxidants in foods. Natural antioxidants have been used instead of synthetic antioxidants to retard lipid oxidation in foods to improve their quality and nutritional value. This review discusses some aspects of recent research on antioxidant activity of plant extracts and natural compounds to impro...

We have recently demonstrated that histone deacetylase inhibitor, Vorinostat, applied as a single therapy or in combination with caspase-8 downregulation exhibits high anti-tumoral activity on endometrial carcinoma cell lines. In the present study, we have assessed the signalling processes underlying anti-tumoral effects of Vorinostat. Increasing evidence suggests that reactive oxygen species a...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

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...

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...

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. this article describes a test method for screening the antioxidant activity of 60 iranian plants o...

Currently, there is global attention focused on finding antioxidants from natural sources, due to common synthetic antioxidants such as butylated hydroxyanisole and butylated hydroxytoluene (BHT) being reported to cause adverse effects including enzymatic and lipid alterations[1]. Antioxidants protect the body from free radicals and reactive oxygen species (ROS). ROS activity leads to skin agei...

Antioxidant activity of methanolic extract of Drynaria quercifolia rhizome at different concentrations (100, 200 and 300μg/ml) were studied in various in vitro models. Results were compared with standard ascorbic acid. Antioxidant activity of extract was increased with the increasing concentration. The order of antioxidant potential according to models were found to be highest in nitric oxide s...
