 (flā′və-noid′)
n.
1. Any of a large group of water-soluble antioxidant compounds, including the anthocyanins, flavonols, flavones, and isoflavonoids, often occurring as glycosides in plants and consisting of two aromatic rings linked by a carbon bridge that often forms a heterocyclic ring. Flavonoids are found in tea, red wine, and a variety of vegetables and fruits.
2. Any of various compounds that are a subset of this group, including the flavones, flavanols, and flavonols, as distinguished from the isoflavonoids. In both senses also called bioflavonoid.

The investigators analyzed the extracts for total phenolic content (gallic acid equivalent--GAE), monomeric anthocyanin content (malvidin-3-glucoside equivalent--MGE) and flavan-3-ol content (catechin equivalent--CE), as well as for their antioxidant capacity (vitamin C equivalent antioxidant capacity--VCEAC) and yield.
