Polyphenol

Representative chemical structure of one of many plant-derived polyphenols that comprise tannic acid. Such compound are formed by esterification of phenylpropanoid-derived gallic acid to a monosaccharide (glucose) core.

Polyphenols (/ˌpɒliˈfnl, -nɒl/) are a large family of naturally occurring phenols.[1] They are abundant in plants and structurally diverse.[1][2][3] Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments.

Curcumin, a bright yellow component of turmeric (Curcuma longa), is a well-studied polyphenol.
