The Antioxidant Activity of Coumarins and Flavonoids
Mini Reviews in Medicinal Chemistry, 2013Coumarins and flavonoids are heterocyclic molecules that have been associated with beneficial effects on human health, such as reducing the risk of cancer, diabetes, cardiovascular and brain diseases. These effects are thought to be related to the radical scavenging effect, due to their antioxidant activities, along with other possible mechanisms, such

Antioxidant activity of Litsea cubeba
Fitoterapia, 2005The antioxidant activity of Litsea cubeba was studied in terms of three different assay systems: DPPH assay, peroxidase/guaiacol assay, and TBA test. The L. cubeba methanol extract and its fractions showed remarkable antioxidant activity in comparison with alpha-tocopherol and ascorbic acid.

Antioxidant Activity of Redox Dyes
Nature, 1955FURTHER evidence has been obtained to support the hypothesis that certain redox dyes, having partial vitamin E activity, can inhibit the catalytic action of haematin in the oxidation of unsaturated fats1.

Antioxidant Activity of Anthocyanins and Their Aglycons
Journal of Agricultural and Food Chemistry, 2003The antioxidant activity of the six common anthocyanidins, pelargonidin, cyanidin, delphinidin, peonidin, petunidin, and malvidin, and their glycosidic forms was evaluated in three lipid-containing models [human low-density lipoprotein (LDL) and bulk and emulsified methyl linoleate]. In addition, the radical scavenging activity of the compounds against

In vitro antioxidant activity of piperine
Methods and Findings in Experimental and Clinical Pharmacology, 2000Oxygen radical injury and lipid peroxidation have been suggested as major causes of atherosclerosis, cancer, liver disease and the aging process. Piperine, having an antiinflammatory effect, has been demonstrated in in vitro experiments to protect against oxidative damage by inhibiting or quenching free radicals and reactive oxygen species and hydroxyl

Antioxidants, NFκB Activation, and Diabetogenesis
Proceedings of the Society for Experimental Biology and Medicine, 1999Abstract.Although many risk factors can trigger the development of insulin‐dependent diabetes (IDDM), it is likely that reactive oxygen species (ROS) play a central role in β‐cell death and disease progression. This review will focus on the role of antioxidant defense systems in the susceptibility to IDDM and on ROS as cellular messengers that regulate

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.

Antioxidant Activity in Cells and Organs
American Review of Respiratory Disease, 1987Abstract Antioxidant activity in cells occurs at several levels. The present work focuses on some aspects of enzymatic antioxidant defense. In particular, the so-called ancillary enzymes and transport systems are presented. Recent aspects on the control of the levels of antioxidant enzymes include the oxyR regulon in microorganisms as
