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...

This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

Soybeans (Glycine max Merr.) were grown at elevated carbon dioxide concentration ([CO(2)]) or chronic elevated ozone concentration ([O(3)]; 90 ppb), and then exposed to an acute O(3) stress (200 ppb for 4 h) in order to test the hypothesis that the atmospheric environment alters the total antioxidant capacity of plants, and their capacity to respond to an acute oxidative stress. Total antioxida...

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: marine algae, especially brown species, produce a wide range of metabolites with various biological activities. objective: since marine algae are rich source of dietary fibers, minerals, proteins, vitamins and phenolic components with antioxidant effect, in addition to the rule of oxidative stress in pathogenesis of chronic diseases, the aim of this study was to investigate possible...

background: fat-rich diet may alter oocyte development and maturation and embryonic development by inducing oxidative stress (os) in follicular environment. objective: to investigate the relationship between fat intake and oxidative stress with oocyte competence and embryo quality. materials and methods: in observational study follicular fluid was collected from 236 women undergoing assisted re...

Antioxidants provide protection against free radicals formed as a result of increased metabolism in living organisms and the damage these cause to cell. For this reason, determining antioxidant levels can help eco-physiologists field understanding physiological state animal at that moment conservation biology. In study, TAC, TOC OSI values 12 Long-legged Buzzards (Buteo rufinus), 7 Common buteo...

Antioxidant capacities of ethylacetate, butanol, and water fractions of peel, pulp, and seeds of Canarium odontophyllum Miq. (CO) were determined using various in vitro antioxidant models. Ethylacetate fraction of peel (EAFPE) exhibited the highest total phenolic (TPC), total flavonoid content (TFC), and antioxidant activities compared to pulp, seeds, and other solvent fractions. Antioxidant ca...

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...
