Antioxidant Activity of Capsinoids
Journal of Agricultural and Food Chemistry, 2002Hot peppers are a good source of dietary antioxidants, encompassing, apart from widespread compounds (flavonoids, phenolic acids, carotenoids, vitamin A, ascorbic acid, tocopherols), also specific constituents such as the pungent capsaicinoids (capsaicin, dihydrocapsaicin, and related analogues).

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

On the antioxidant activity of melatonin
Free Radical Biology and Medicine, 1999Melatonin has been widely reported to be an effective antioxidant. Studies of its ability to inhibit the autoxidation of lipids in homogeneous solution and in model heterogeneous systems show that melatonin is not a peroxyl radical trapping antioxidant. In contrast, melatonin can inhibit metal ion-catalyzed oxidation processes.

Antioxidant activity of propylthiouracil
Free Radical Biology and Medicine, 1990Propylthiouracil (PTU) has been demonstrated to reduce alcohol-induced hepatocyte damage and severe alcoholic liver disease. Although the mechanism by which the drug operates is yet to be elucidated, there is evidence that PTU may act as an antioxidant.

The antioxidant activity of caroverine
Biochemical Pharmacology, 2003Caroverine, 1-(2-diethylaminoethyl)-3-(p-methoxy benzyl)-1,2-dihydro-2-quinoxalin-2-on-hydrochloride, is a class B calcium-channel-blocker and antiglutamatergic agent with significant effects on the brain function. Caroverine exhibits competitive AMPA antagonism, and at higher concentrations, noncompetitive NMDA antagonism.

Antioxidant Activity of Grains
Journal of Agricultural and Food Chemistry, 2002Epidemiological studies have shown that consumption of whole grains and grain-based products is associated with reduced risk of chronic diseases. The health benefits of whole grains are attributed in part to their unique phytochemical composition. However, the phytochemical contents in grains have been commonly underestimated in the literature, because

Antioxidant activity of carotenoids
Molecular Aspects of Medicine, 2003Carotenoids are pigments which play a major role in the protection of plants against photooxidative processes. They are efficient antioxidants scavenging singlet molecular oxygen and peroxyl radicals. In the human organism, carotenoids are part of the antioxidant defense system.

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.
