in this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (malus domestica) skin and flesh of six iranian cultivars, including: ‘golab kohanz’, ‘sib torsh dirras’, ‘ghara yapragh’, ‘torkman’, ‘ghezel alma’ and ‘abbasi mashhad’, and four commercial cultivars including: ‘golden delicious’, ‘red delicious’, ‘braeburn’ a...

xanthine oxidase plays crucial roles in the production of reactive oxygen species (ros), and uric acid in blood which may lead to gout, one of the oldest known forms of arthritis amongst humans. summer savory (satureja hortensis l.) a medicinal/spice exhibits antioxidant activity, but unknown effects on xanthine oxidase activity. here, for the first time, we examined the effects of s. hortensis...

abstract in this study, the physicochemical quality and antioxidant activities of fruits peel from 6 citrus varieties which commonly consumed in the north of iran were determined. some parameters were measurement such fruit size, peel thickness, residue percentage, peel color indices, total phenolics, total flavonoid, total anthocyanins, total carotenoids, total chlorophyll, ascorbic acid conte...

the production of reactive oxygen species (ros) in plants under low temperature stress cause damage to plants. in order to evaluate of antioxidant responses of page mandarin young trees (two years old) on different rootstocks under low temperatures, an experiment was conducted in a factorial plan based on completely randomized design. treatment of temperatures were at seven levels include 9, 6,...

Methanol 70% extract of Bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. The results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of Bacillus subtilis and...

enhancement of antioxidant capacity of plants by natural antioxidants obtained from medicinal plants can be a simple way to produce stress tolerant plants. zataria multiflora essential oil (zo) is one of the useful antioxidants with potent antioxidant activity. zo is insoluble in water and can be degraded by light, oxygen, and high temperature. incorporation of zo into poly vinyl alcohol (pva) ...

the aim of this study was to investigate the stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. the volatile constituents from the aerial parts of stachys turcomanica growing wild in iran were obtained by hydrodistillation and analyzed by gc and gc-ms. in the gc-ms analysis, forty-six components representing 81.1% of the oil were identifie...

this study represents the first report on the chemical composition and biological activity of trifolium angustifolium var. angustifolium. the major components of the essential oil were identified as hexatriacontene (23.0%), arachidic acid (15.5%) and α-selinene (10.0%). the main constituents of the fatty acid obtained from the petroleum ether extract were identified as palmitic acid (29.8%), li...
