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...

objective: oxidative stress is involved in the pathophysiology of diabetes and cardiovascular complications of metabolic syndrome. the main objective of this study was to evaluate total antioxidant status by diphenylpicrylhydrazyl (dpph)-scavenging activity in patients developed metabolic syndrome (mets). materials and methods: forty-four patients with mets diagnosed on the basis of adult treat...

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...

in this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of nerium oleander l. grown in the north of iran by employing various in-vitro assay, i.e. dpph free radical scavenging, reducing power and total antioxidant capacity through the mo (vi) reduction. the extracts showed different level...

background: development of safe radioprotector is a challenging task. in this study radioprotective effect of sucrose has been demonstrated in calf thymus dna (ctdna). sucrose is a free radical scavenger and also acts as osmolyte and therefore can influence the water activity around dna and effects of radiation on dna. hoechst 33258 was used to probe the possible alteration in physicochemical p...

the plants of the genus salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. eleven salvia species including s. aegyptiaca, s. aethiopis, s. atropatana, s. eremophila, s. hypoleuca, s. limbata, s. nemorosa, s. santolinifolia, s. sclarea, s. syriaca, and s. xanthocheila ...

the subject handled in this study is the determination of antioxidant activities of extracts obtained from the urginea maritima (l.) baker plant’s leaves and tubers. extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. the antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. moreover, the free radical scavenging ...

lemon verbena (lippia citriodora) belongs tothe verbenaceae (shahpasand) family.l.citriodora is chemical  composition of the leaves plant have antimicrobial properties, refrigerant,anti-headaches one-sided, anti- pains nerve and housing, carminative, helping to digestion, relaxation, dizziness, colds therapy,  memory booster and etc.  in this study, phenolic compounds of l.citriodoraleaves were...

the antioxidant potential of crude methanol extract (ce) as well as chloroform (cf), ethyl acetate (ef) and n-butanol (nf) soluble fractions of enhydra fluctuans lour, which is widely used in indigenous system of medicine for different purposes, were studied. the antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. in addition, total a...
