Total phenolic contents (TPC) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of Artemisia biennis Willd were measured in this work. The antioxidant activity was investigated by three different methods: β-carotene bleaching (BCB) test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and ferrous ion chelating (FIC) assay. Amo...

plants are almost reach sources of phenolic compounds such as flavonoids which are the most importantnatural antioxidants. antioxidant compounds are essential for protecting human body against oxidativestress. however use elicitors could increase the antioxidant activity of plant. the purpose of this studywas to evaluate the effects of chitosan on the content of phenolic and flavonoid compounds...
The present study aimed at investigating the influence of several production factors, conservation conditions, and extraction procedures on the phenolic compounds and antioxidant activity of blueberries from different cultivars. The experimental data was used to train artificial neural networks, using a feed-forward model, which gave information about the variables affecting the antioxidant...
Aim of this paper is to find out the relationship between antioxidant activity of Abutilon indicum Linn and their phytochemical composition especially phenols and flavonols. Successive extractions were carried out for the Abutilon indicum plant with petroleum ether, chloroform, ethyl acetate, n-butanol, ethanol and water. All these extracts were evaluated for their antioxidant activities. Their...
Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...
conclusions further investigations are needed about favorable composition of unsaturated fatty acids and flavonoid content of leaves of s. paradoxa. in addition, due to high phenolic content of the leaves, s. paradoxa is a promising source of natural antioxidants and may play good antidiabetic activity. results the amount of total phenolic compounds was higher in leaves than roots. besides, roo...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
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...
Three native Turkish medicinal and aromatic plants (Artemisia absinthum, Artemisia santonicum and Saponaria officinalis) were investigated to analyze their antioxidant activity, total phenolic content and antimicrobial activity. Their total antioxidant activity was determined by using a β-carotene bleaching assay and their antimicrobial activity was determined by utilizing an agar disc diffusio...
