The aim of this study was to determine the in vitro antioxidant activity, free radical scavenging property and the beneficial effects of extracts of various parts of Syzygium guineense in reducing oxidative stress damage in the liver. The effects of extracts on free radicals were determined on radicals DPPH, ABTS, NO and OH followed by the antioxidant properties using Ferric Reducing Antioxidan...

The antioxidant activities of 70% acetone extract (70% AE) from the hypocotyls of the mangrove plant Kandelia candel and its fractions of petroleum ether (PF), ethyl acetate (EF), water (WF), and the LF (WF fraction further purified through a Sephadex LH-20 column), were investigated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing/antioxidant power (FRAP)...

it has been investigated the in vitro antioxidant properties of ethanol extracts of the contained-allantoin plants in this study. contained-allantoined plant samples plantago lanceolata, plantago major, robinia pseudoacacia, platanus orientalis and aesculus hippocastanum were tested at different concentrations. the antioxidant activities of plant samples were analysed by 1,1- diphenyl-2-picrylh...

Medicinal plants have a lot of type antioxidants, mostly polyphenols, flavonoids which exhibit high antioxidant activity (Rice-Evans et al. 1995). The intake of antioxidants present in food is an important health-protecting factor. Herbal compounds known by ancient medicine are of growing interest in the domain of prevention of diseases. The FRAP assay (ferric reducing ability of plasma), a sim...

Objective: Type 2 diabetes mellitus (T2DM) is a multifactorial disorder with various disturbances in biochemical processes such as antioxidant status and lipid peroxidation. The aim of present study was evaluation of the oxidative stress markers in saliva of T2DM patients. Materials and Methods: In this study, 80 (40 T2DM and 40 control) individuals were assessed. The salivary total antioxidan...

The powder samples and methanol extract of 11 medicinal plants were subjected to analysis of proximate composition and measurement of antioxidant activity. Different parameters studied include phenolic contents, moisture, ash, crude fiber, fats and waxes. The assays employed were ferric reducing antioxidant power, trolox equivalent antioxidant capacity and scavenging effect on the 1,1-diphenyl-...

Objective: Boerhaavia elegans L. (Nyctaginaceae) is a medicinal plant used for the treatment of kidney disorders, urinary tract disorders and blood purification in Baluch tribe. The aim of present study is to evaluate the antioxidant propertyof B. elegans species for the first time. Materials and Methods: Different parts (leaf, stem and fruit) of the plant were extracted by using various solven...

N-Hydroxycinnamoylphenalkylamides (36H) exhibited both antioxidation and antityrosinase abilities. The compound was studied for its antioxidative properties, using a 1,1-diphenyl-2-picrylhydrazul- (DPPH-) scavenging test, a ferric ion-reducing antioxidant power assay (FRAP) assessment, and a metal-chelating power assay. The results showed that 36H had antioxidative capabilities in the DPPH-scav...

A synthesis of 2-((4-phenyl-5-(2-(p-tolylamino)ethyl)-4H-1,2,4-triazol-3-yl)thio)-N’-(1-phenylethylidene)acetohydrazide from 2-[(3-{2-[(4-methylphenyl)amino]ethyl}-4-phenyl-4,5-dihydro-1H-1,2,4-triazol-5-yl)sulfanyl]acetohydrazide and acetophenone is reported. The title compound has been tested to possess 1.5-fold higher antioxidant ability than the control, butylated hydroxytoluene, as determi...

in this study antioxidant activity of the red algae (hypnea hamulosa) was investigated in the invitro condition. the measurement included total phenolic content, ferric reducing power, dpph radical scavenging activity and total antioxidant activity. seaweed samples with the ratio of 1:20 (algae: solvent) were extracted using conventional solvent extraction method for 24 hours. the applied solve...
