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...

background: a high percentage of patients admitted to the intensive care unit (icu) have systemic inflammatory response syndrome (sirs) criteria. free radicals play an important role in initiation and development of sirs. the purpose of this study was to assess and compare the molecular changes of cellular antioxidant power in patients with sirs who received enteral nutrition (en) or en combine...

In this study, in vitro antioxidant activity, total phenolic content and concentration of flavonoids of five different extracts, from the whole herb of Marrubium peregrinum L. (Lamiaceae) were determined using spectrophotometric methods. Antioxidant activity of extracts were expressed as percentage of DPPH radicals inhibition and IC50 values (μg/ml). Values in percentage ranged from 27.26 to 89...

The present study was designed to evaluate and compare the phenolic (total phenols and flavonoid) contents and antioxidant activity of aqueous extract of Momordica foetida (AEMF) and ethanolic extract of Momordica foetida (EEMF) extract of Momordica foetida leaves; a popular medicinal plant used for traditional medicine preparations. The antioxidant activity of both extracts was assessed using ...

objective(s) comparison of prooxidant-antioxidant balance (pab) assay with crocin assay. materials and methods twenty eight serum samples were chosen, pab and the total antioxidant capacity were measured by pab assay and crocin, respectively, and the correlation of both assays, along with their correlation with other clinical and biochemical parameters, were determined. results a significant ne...

background: leukoplakia is a common, potentially premalignant lesion with malignant transformation rate from 1 to 17% with highest transformation rate for the lesions on the floor of the mouth, soft palate and tongue. one of the main etiological factors is consuming areca nut and its commercial preparations which generate high levels of reactive oxygen species during their metabolism. so the ai...

Sweet potato is known to be rich in healthful antioxidants, but the stability of its antioxidant properties under gastrointestinal pH is very much unknown. Hence, this study aimed to evaluate the changes in antioxidant properties (total contents of phenolics and flavonoids as well as antioxidant activity) of sweet potato flour (SPF) under simulated gastrointestinal pH conditions. It was found t...

Various extracts of local marine red algae, Acanthophora spicifera were evaluated for antioxidant activity, total phenolic content and in-vitro toxicity. The antioxidant activity was measured using DPPH (1, 1-diphenyl-2-picrylhidrazyl) method, while Folin-Ciocalteu method was used for the total phenolic content. The cytotoxicity of the extracts were evaluated using invitro brine shrimp lethalit...

The aim of this study was to compare the contents of the main biochemical compounds and the antioxidant capacity of five Spanish olive oils by four different antioxidant tests and to find out the most valuable oil for disease preventing diets. Fatty acids, sterols and individual antioxidant compounds in Arbequina, Hojiblanca, Extra Virgin, Picual and Lampante Spanish olive oils were determined....

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 ...
