Lamiaceae is one of the largest families in plant kingdom, including genus Stachys and Scutellaria, which are used many folk medicines throughout world for prevention also treatment several disorders. In vitro biological potential iberica subsp. stenostachya Scutellaria orientalis sosnowskyi were investigated current study. The aerial parts plants extracted using different solvents such as n-he...

BACKGROUND The objective of the present study was to determine the phytochemical content and the protective effect of red grape skin extract (RGSE) against fructose-mediated protein oxidation. In addition, RGSE was screened for its potential as an antioxidant using various in vitro models. METHODS Antioxidant activity was measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl radical scav...

A simplified procedure is described for the determination of inorganic phosphate in body fluids. The method employs two stable reagents and requires a minimum number of steps. Serum is deproteinized with trichioroacetic acid containing ferrous ion and thiourea. The supernatant is decanted and mixed with a small volume of molybdic acid. The phosphomolybdate formed is immediately reduced in situ ...

PURPOSE The aim of present in vitro studies was performed to examine the antioxidant and anticancer activities of ethanol and aqueous extracts of Drosera indica L. METHODS Different concentrations (5 - 640mcg/ml) of the ethanol (EEDI) and aqueous (AEDI) extracts of D.indica L were used in various antioxidant assay methods such as hydroxyl radicals, DPPH, super oxide radical scavenging activit...

Iron and copper are essential for plants and are important for the function of a number of protein complexes involved in photosynthesis and respiration. As the molecular mechanisms that control uptake, trafficking and storage of these nutrients emerge, the importance of metalloreductase-catalyzed reactions in iron and copper metabolism has become clear. This review focuses on the ferric reducta...

Background: Thymus persicus is one of the Iranian endemic medicinal plants, that its decoction and various products have plenty of food and pharmaceutical uses. Objective: Evaluation of T. persicus products metabolite contains and determination of the best antioxidant, anti-diabetic and anti-Alzheimer extract. Methods: Samples total phenolic, flavonoid and tannin contents were determined by F...

Elevated serum iron level is linked with an increased risk of diabetes and atherosclerosis. However, the pathological mechanism by which iron affects serum lipoprotein levels is unknown. To elucidate the mechanism, a high dose of ferrous ion was applied (final 60 µM, 120 µM) to human serum lipoproteins, macrophages, and human dermal fibroblast (HDF) cells. Iron-treated lipoproteins showed loss ...

Thiobacillus ferrooxidans cells grown on sulfur, pyrite, and chalcopyrite exhibit greater hydrophobicity than ferrous ion-grown cells. The isoelectric points of sulfur-, pyrite-, and chalcopyrite-grown cells were observed to be at a pH higher than that for ferrous ion-grown cells. Microbe-mineral interactions result in change in the surface chemistry of the organism as well as that of the miner...

the present work is carried out to study the antioxidant potential of ethanolic extract of alstonia scholaris linn. ( apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (dpph . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   ethanolic extract of alstonia...

Schizophyllum commune is a widely distributed macrofungal species assorted with bioactivities. The specific objectives were evaluation of antibacterial and antioxidant properties, synthesis exopolysaccharides carbohydrates contents estimation mycelial extract S. under submerged condition. Methanolic extracts identified showed highest FRS (92.59%), chelating effect on ferrous ion (79.36%), reduc...
