Biological effects of essential oils - A review
TL;DR: Findings suggest that, at least in part, the encountered beneficial effects of essential oils are due to prooxidant effects on the cellular level.

The conversion of procyanidins and prodelphinidins to cyanidin and delphinidin
TL;DR: In this article, a standard method of analysis of proanthocyanidins based on use of an n-BuOH-HCl-FeIII mixture is given, and the ratio of absorbance maxima of the cyanidin (550 nm) produced to that near 280 nm for the original procyanidin polymer solution was ∼ 3.5.

Flavonoids, a class of natural products of high pharmacological potency
TL;DR: The few existing reports on the careful pharmacodynamic, pharmacokinetic and clinical studies which have been made have been summarized to provide a basis for a full-scale investigation of the therapeutic potential of flavonoids.

Flavonoid (myricetin, quercetin, kaempferol, luteolin, and apigenin) content of edible tropical plants.
Koo Hui Miean,Suhaila Mohamed +1 more
TL;DR: In vegetables, quercetin glycosides predominate, but glycoside of kaempferol, luteolin, and apigenin are also present, whereas fruits contain almost exclusively quERCetin Glycosides, whereas kaempfol and myricetinglycosides are found only in trace quantities.

Antioxidant and antiradical activities of flavonoids.
Stanisław Burda,Wieslaw Oleszek +1 more
TL;DR: From seven structurally divergent groups of flavonoids, only flavonols with a free hydroxyl group at the C-3 position of the flavonoid skeleton showed high inhibitory activity to beta-carotene oxidation.
