Mucolytics and antioxidant activity
Life Sciences, 1999We investigated effects of the mucolytics ambroxol and N-acetylcysteine on airways reactivity evoked by histamine in guinea pigs exposed to toluene vapors. We did not find significant changes in reactivity of tracheal smooth muscle from animals treated with mucolytics compared to the control group.

Antioxidant Activity of Diethyldithiocarbamate
Free Radical Research, 1996Diethyldithiocarbamate (DDC), a potent copper chelating agent, has long been used for the treatment of oxygen toxicity to the central nervous system, as an immunomodulator to treat cancer, and in HIV-infected patients. We evaluated the antioxidant properties of DDC, including its scavenging of reactive oxygen species, its reducing properties, its iron ...

Antioxidant Compounds and Antioxidant Activity in “Early Potatoes”
Journal of Agricultural and Food Chemistry, 2008The antioxidant content and the antioxidant capacity of both hydrophilic and lipophilic antioxidant extracts from four "early potato" cultivars, grown in two different locations (Racale and Monteroni), were examined. There was a considerable variation in carotenoid content and weak differences in the ascorbic acid concentration of the examined ...

Antioxidant Activity of Essential Oils
Journal of Agricultural and Food Chemistry, 2013Essential oils (EOs) are liquid mixtures of volatile compounds obtained from aromatic plants. Many EOs have antioxidant properties, and the use of EOs as natural antioxidants is a field of growing interest because some synthetic antioxidants such as BHA and BHT are now suspected to be potentially harmful to human health.

Antioxidant activity and active sites of phospholipids as antioxidants
Journal of the American Oil Chemists' Society, 1997AbstractVarious compounds, representative of the major functional groups in phospholipids, phosphatidylethanolamine and phosphatidylcholine, were tested for antioxidant activity (AA) in a sardine oil system to determine the relationship between molecular structure and the AA of these compounds. AA was found to be attributable not only to the side‐chain

Antioxidants are groups of substances able to prevent and delay the oxidation of easily oxidizable molecules and avoid free radicals’ formation. In living organisms, the main free radicals are reactive oxygen species and reactive nitrogen species. At low levels, they are involved in the regulation of diverse physiological processes, but an imbalance ...

Antioxidant activity of retinoids
1990Publisher Summary Although the effects of retinoids are numerous in biological systems, among them are indications that retinoids may exert some of their actions by virtue of their acting as lipid-soluble antioxidants. In evaluating a substance as an antioxidant, it is important to use more than one assay, because an antioxidant may be very sensitive

Antioxidant activity of Erica arborea
Fitoterapia, 2007The antioxidant properties of the methanol extract of leaves and flowers of Erica arborea and the ethyl acetate, butanol and water soluble fractions were investigated. The ethyl acetate extract was found to be the richest for phenolic and flavonoid content which showed the highest antioxidant activity.
