BACKGROUND Pterostilbene, a methoxylated analog of Resveratrol, is gradually gaining more importance as a therapeutic drug owing to its higher lipophilicity, bioavailability and biological activity than Resveratrol. This study was undertaken to characterize its ability to scavenge free radicals such as superoxide, hydroxyl and hydrogen peroxide and to protect bio-molecules within a cell against...

Purpose: To explore the antioxidant properties of the methanol extract of Pericarpium Zanthoxyli and its effect on inducible nitric oxide synthase (iNOS), cycleooxygenase-2 (COX-2) and lipopolysaccharides (LPS)-induced cell damage in macrophage cells. Methods: Anti-oxidant activities were tested by measuring free radical scavenging activity (DPPH, NO) and lipid peroxidation levels. The mechanis...

Buckwheat sprouts contain various bioactive compounds including rutin which have a number of biological activities. We have previously shown that buckwheat sprouts (TBWE) treated with methyl jasmonate (MeJA) significantly increased the amount of phenolics and the antioxidant activity. The aim of this study was to demonstrate the effect of TBWE on anti-adipogenesis and pro-oxidant enzyme in 3T3-...

BACKGROUND Lecythis pisonis Cambess is commonly known as "castanha de sapucaia" in Brazil. Chemical composition studies revealed that this nut is an excellent source of anti-oxidant minerals and of essential lipids. OBJECTIVE The aim of the present study is to assess the anti-oxidant and anti-inflammatory effect of Lecythis pisonis Cambess on the brain tissue of Wistar rats. MATERIAL AND ME...

Adverse drug reactions with an immunological basis (ADRIB) may involve activation of other concomitant, non-specific mechanisms, amplifying the specific response and contributing to the severity and duration. One concomitant mechanism could be the generation of reactive oxygen species (ROS) and/or their detoxification by anti-oxidants, including anti-oxidant enzymes. We analysed the activity of...

The compounds Gallic acid (GA), rutin(R), quercitin (Q), ellagic acid (EA) and sitosterol(S) were isolated from the methanolic extract of the leaves of Tectona grandis. These compounds were subjected to antimicrobial and antioxidant activity. The zone of inhibition of isolated compounds was evaluated by cup plate method against bacteria i.e. Staphylococcus aureus, Bacillus subtilis, Eschericia ...

Purpose: To investigate the anti-dyslipidemic, anti-oxidant and anti-diabetic activities of the aqueous extract and solvent fractions of A. violacea flowers. Methods: The aqueous extract was fractionated into petroleum ether, ether, chloroform, chloroformmethanol (4:1) and chloroform-methanol (3:2) fractions. Lipid lowering activity was evaluated in two models, viz, triton WR-1339 induced hyper...

The traditional medical system has made extensive use of plants and naturally occurring compounds derived from plants. plant been discovered to be phyto chemically abundant in tannins, terpenes, terpenoids, phenolic compounds, phytosterols, a variety new metabolites that have displayed notable pharmacological effects. Lumnitzera racemosa wild is non-viviparous evergreen shrub or small tree, an ...
