objectives: leaves and flowers ofelaeagnus angustifolia contain phenolic and flavonoid compounds. these compounds have antioxidant properties that protect cells from oxidative damage. the aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two e. angustifolia variants using different solvents (ethanol and methanol). materials and methods:...

background there is an interest in finding new and safe antioxidants from natural sources such as medicinal plants. objectives the aim of this study was to evaluate the antioxidant activity of ten iranian medicinal plants extracts. materials and methods for antioxidant activity, the radical scavenging activity, reducing power and phenolic contents of ethanol plant extracts were determined. gall...

plants are rich source of phenolic compounds (phenolic acids, flavonoids and tannins) that are most important natural antioxidants. in the present study two ultrasonic methods including probe and bath were used for the extraction of phenolic and flavonoid compounds from celtis australis. the effects of different extraction time including 30, 60 and 90 min (bath method) and 5, 10 and 20 min (pro...

fats and oils are made of triglycerides. the fatty acids are the main constituents of triglycerides. there are minor components present in the oils and fats that are of great importance in human health, namely tocopherols and phenolic compounds that exhibit antioxidant activities. the concentrations of these compounds vary during ripening and maturation of olives. the object of the present stud...

this study investigated the fatty acids profile, oxidative stability indices, and bioactive compounds of virgin and processed olive oils (leccino and frantoio cultivars). results showed that fatty acid profile of the studied oils contained mostly oleic acid followed by palmitic and linoleic acid. acid values of virgin frantoio and processed leccino were 0.78 and 0.18 mg koh/g oil, with peroxide...

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...
