the present study was carried out to evaluate the hepatoprotective and antioxidant effect of the methanol extract of eupatorium ayapana (meea) (family- asteraceae) leaves in wistar albino rats. the different groups of animals were administered with carbon tetrachloride (ccl4) at 72 h interval.  the meea at 100, 200 and 300 mg/kg and silymarin 25 mg/kg were administered to the ccl4 treated rats....

BACKGROUND Limited observational evidence suggests lower antioxidant concentrations in individuals with the metabolic syndrome (MetS); few randomized controlled trials have addressed the effect of multiple antioxidants on the risk of MetS. OBJECTIVE The objective was to examine the effect of antioxidant supplementation for 7.5 y on the incidence of MetS and the epidemiologic association betwe...

standardization of induction of oxidative stress with fenton mixture (fm) in isolated perfused rat kidney and the antioxidant effect of terminalia arjuna bark in the isolated oxidatively stressed rat kidney has been evaluated. six groups each containing eight isolated perfused rat kidneys were used for the present study and the oxidative stress was induced by perfusing the isolated kidneys with...

Airway mucosal surfaces are potentially subjected to a variety of oxidant stresses. Airway submucosal glands secrete a variety of compounds that may protect the airways from injury. Cholinergically induced nasal submucosal gland secretion has recently been found to contain a low molecular weight nasal antioxidant. In this report, the isolation and identification of this nasal secretory antioxid...

The objective of this study was to explore the antioxidant levels and anticancer properties of chicory cultivated using three different kinds of fertilizers (i.e., developed, organic, and chemical) in the presence and absence of pesticides. Phenolic phytochemicals, including total polyphenols and flavonoids, and antioxidant activities, including reducing power, ABTS+ and DPPH radical scavenging...

An imbalance in the reactive oxygen species (ROS) homeostasis is involved in the pathogenesis of oxidative stress-related diseases. Astaxanthin, a xanthophyll carotenoid with high antioxidant capacities, has been shown to prevent the first stages of oxidative stress. Here, we evaluate the antioxidant capacities of astaxanthin included within hydroxypropyl-beta-cyclodextrin (CD-A) to directly an...

Epidemiologic studies suggest an inverse association of tea consumption with cardiovascular disease. The antioxidant effects of flavonoids in tea (including preventing oxidative damage to LDL) are among the potential mechanisms that could underlie the protective effects. Other possible mechanisms include attenuating the inflammatory process in atherosclerosis, reducing thrombosis, promoting nor...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

the side effects of synthetic antioxidants have been considered in different studies. accordingly, there is an increasing interest toward the use of natural substances instead of the synthetic ones. in this study, the aqueous and ethanolic extracts of pistacia vera leaves and fruits as well as hydroalcoholic extract of gum were tested for a possible antioxidant activity using in vitro methods. ...

Background & Aim: Chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. In this study, the effect of essential oil from Heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated. Experimental: The essential oil of H. lasiopetalum extracted usin...
