TLDR
Hydrophilic phenols are the most abundant natural antioxidants of virgin olive oil, in which, however, tocopherols and carotenes are also present.Abstract:
Hydrophilic phenols are the most abundant natural antioxidants of virgin olive oil (VOO), in which, however, tocopherols and carotenes are also present. The prevalent classes of hydrophilic phenols found in VOO are phenolic alcohols and acids, flavonoids, lignans and secoiridoids. Among these substances the last two classes include the most concentrate phenols of VOO. Secoiridoids, like aglycone derivatives of oleuropein, demethyloleuropein and ligstroside, are present in olive fruit as most abundant VOO phenolic antioxidants. Several important biological properties (antioxidant, anti-inflammatory, chemopreventive and anti-cancer) and the characteristic pungent and bitter tasty properties have been attributed to VOO phenols. Relationships between polyphenols activities and their chemical structures are discussed in this paper.read more

TL;DR: Enzymes associated with HDL may play an important role in protecting against lipid oxidation in the artery wall and may account in part for the inverse relation between HDL and risk for atherosclerotic clinical events.

The Mechanism of Antioxidant Action in Vitro
TL;DR: The spontaneous reaction of atmospheric oxygen with organic compounds leads to a number of degradative changes that reduce the lifetime of many products of interest to the chemical industry, especially polymers, as well as causing the deterioration of lipids in foods.

TL;DR: Selegiline may act through a mechanism unrelated to MAO-B to increase neurotrophic factor activity and upregulate molecules such as glutathione, SOD, catalase, and BCL-2 protein, which protect against oxidant stress and apoptosis.

TL;DR: It is shown that newly pressed extra-virgin olive oil contains oleocanthal, a compound whose pungency induces a strong stinging sensation in the throat, not unlike that caused by solutions of the non-steroidal anti-inflammatory drug ibuprofen, which is an indicator of a shared pharmacological activity.

TL;DR: Evidence is presented that it is the unique profile of the phenolic fraction, along with high intakes of squalene and the monounsaturated fatty acid, oleic acid, which confer its health-promoting properties.
