ABSTRACT Three 2'-aminochalcone derivatives (E)-1-(2-aminophenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one, (E)-1-(2-aminophenyl)-3-(3,4-dihydroxyphenyl)prop-2-en-1-one, and (E)-1-(2-amino-4,5-dimethoxyphenyl)-3-(4-methoxyphenyl)prop-2-en-1-one, have been synthesized, characterized, and tested in vitro in order to assess their antioxidant activity. All compounds were characterized on the basis of 1H ...

The antioxidant activity and phenolic composition of six in vitro cultured blueberry seedlings were determined. Extracts were prepared in 85% ethanol from 30 days old in vitro cultured plants and used to evaluate the antioxidant capacities that included Ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazin (DPPH•) scavenging ability, total polyphenols (TP) and the partial p...

In this study, ultrasound-assisted extraction of green pea pod polysaccharide (GPPP) was investigated and optimized using a central composite response surface design coupled with a numerical optimization technique. The effects of ultrasonic power (50-150 W), sonication time (20-80 min), ratio of water to raw material (20:1-40:1 mL/g) and extraction temperature (40-80 °C) on polysaccharide extra...

Background: Non-steroidal anti-inflammatory drugs (NSAID) have been associated with antioxidant property and have been shown to improve the circulating antioxidant status on daily dosing in different inflammatory conditions. The present study was conducted to investigate the antioxidant role of meloxicam in aluminum induced oxidative stress in rat brain. Methods: In the in vivo experiments, Spr...

The present study was conducted to determine the antioxidant and antifungal effects ofmethanol extract from aerial part of Verbascum speciosum. The total phenolic andflavonoid content and the antioxidant activity of the plant extract were determined byusing the Folin-Ciocalteau and the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radicalscavenging assays. The total phenols and flavonoid content o...

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...

haptoglobin (hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. as an important consequence, haptoglobin-hemoglobin complex (hp-hb) shows considerable antiox...
