abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...

human milk contains all of the constituents that are required for the optimal growth and development of a neonate. it supports the development of brain, immune, and physiological systems. this study aimed to consider the significance of breast milk in preventing oxidative stress by comparing total antioxidant capacity (tac) in breast and formula milk for premature infants, demonstrating the rel...

the essential oil from the aerial parts ofjurinea leptoloba dc., collected from shiraz (south of iran), was investigated for total phenolic content (tpc), antioxidant and cytotoxic effects. tpc of j. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg gae/mg oil) using the folin-ciocalteau assay. the ferric reducing power of the oil was determined 0.117 ± 0.0...

herbal medicines can be used as the potential sources of anti-oxidative compounds to help the treatment of diseases associated to oxidative stress. in this paper, the ferric reducing antioxidant power (frap) activity of four lamiaceae herbal extracts, which traditionally applied in oxidative stress related diseases, has been evaluated and total phenolics contents of these extracts determined by...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...

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...

abstract introduction: medicinal plants belong to lamiaceae family are potential sources of new drugs to improve the treatment of diseases which its treatment is linked to anti-oxidative agents. in this paper, antioxidant potentials of some lamiaceae species have been evaluated by two methods. methods: phosphomolybdate assay for total antioxidant capacity and ferric reducing antioxidant potenti...

the genus phoenix is one of the most widely cultivated groups of palms around the world. the aim of this study was to determine the antioxidant activity and total phenolic compounds of 14 different varieties of date palm (phoenix dactylifera l., arecaceae) seed extracts with 5 solvents [water, methanol, methanol (50%), dmso, and water: methanol: acetone: formic acid (20:40:40:0.1)]. ferric redu...

phytochemical constituents, such as total phenol, allicin and pyrovic acid as well as antioxidant activity of thirteen ecotypes of allium hirtifolium boiss. from different regions of iran were evaluated. average contents of total phenol, allicin and pyrovic acid of bulbs extracts per g fresh weight were 0.647 mg gallic acid equivalent (gae), 2.127 mg and 84.412 µmol, respectively and antioxidan...
