this study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of salix aegyptiaca l. grown in iran. the methanolic extract (me) and its three fractions including water (wf), butanol (bf) and chloroform (cf) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

introduction: increasing of food-related diseases has led to the perception of diet importance. plant-derived products (especially tea) as important sources of antioxidant and antimicrobial compounds play a major role in reducing food pathogens. in this study, total phenolic content, antioxidant and antimicrobial activity of four tea extracts including green tea, white, black and red teas were ...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...

Oxidative stress plays important roles in a wide spectrum of pathological processes, such as atherosclerosis. Although several environmental factors are documented to influence redox metabolism, relatively little is known about genetic effects. In the present study, we evaluated genetic contributions to variation in plasma total antioxidant status (TAS), a measure of peroxyl-scavenging capacity...

The objective of this study was to evaluate total phenolic content and antioxidant activity of leaf and different parts of fruit (hull, shell, and kernel) of Bene in Ilam province. Total phenolic content was determined with the Folin- Ciocalteu Reagent (FCR); antioxidant activity of methanolic extracts were examined by DPPH (2,2diphenyl- 1- picrylhydrazyl), FRAP (ferric reducing antioxidant pow...

the aim followed in the present study was to evaluate the antioxidant activity of individual vs. combined extracts of rosemary leaves and oak fruit to detect the possible interactions in their antioxidant activity following combination and in order to find a way to use oak fruit natural antioxidants as an available massive source in iran. towards this end, methanolic extracts of rosemary and oa...

Grapes are significant sources of nutritional antioxidants as well as biologically active dietary components. This study was carried out to determine the amount of total phenols, anthocyanins and antioxidant activity of 35 grapevine (Vitis vinifera L.) cultivars grown in Fars province (Iran). Ripened bunches were randomly harvested from grapevine collection in Zarghan (Fars province, Iran) Agri...

plants with hypoglycemic properties are important in the treatment of diabetes. one of the mechanisms in reducing blood glucose is preventing the digestive absorption of glucose. the aim of this study was to evaluate the antioxidant properties of some traditional medicinal plants collected from different regions of iran and their effects on glucose diffusion decrease. the amounts of phenolic co...

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...
