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...

background & aim: medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. the aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. experimental: for determination of free radical scavenging activity was...

the oxidative stress causes many diseases in human, therefore antioxidants have a specialposition in the medicinal chemistry. tyrosol is an important antioxidant with a plenty ofbiological properties. there are many strategies such as clustering single drug units in orderto develop new drugs. the cluster effect can increase drug effects relative to single drug unit.calixtyrosol is the novel clu...

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...

objectives: potato (solanum tuberosum l.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. the objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (solanum tuberosum) cultivars in iran i.e., savalan, agria and sante. materials and methods: phenol...

piriformospora indica, a cultivable root colonizing endophytic fungus of sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. the fungus has also the ability to colonize the roots of many varieties of plant species. the goal of present study was to clarify the colonization ability of p.indica in artichoke roots and the respond of plant to water stress. re...

the present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of dryopteris erythrosora. the total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. all extracts from different parts of d. erythrosora showed strong bioactivities. the dpph free radical scaven...

objectives: almond (prunus amygdalus) hull and shell are agricultural by-products that are a source of phenolic compounds.the processing of almond produce shell and hull, accounts for more than 50% by dry weight of the almond fruits. recently, more studies have focused on the influence of storage conditions and postharvest handling on the nutritional quality of fruits, especially the antioxidan...

this research was carried out to assess the effect of drought stress on head branch dry weight, photosynthesis, essential oil yield and radical scavenging of rosemary (rosmarinus officinalis l.) in islamic azad university, shoushtar branch, iran during 2010-2011.the experiments were carried out using complete randomized block design with four replications and drought stress levels included cont...
