Galloyl glucose
Galloyl glucose, also known as 1-galloyl-beta-D-glucose or beta-glucogallin, is a member of the class of compounds known as tannins. Tannins are naturally occurring polyphenols which be categorized into four main classes: hydrolyzable tannin (based on ellagic acid or gallic acid), condensed tannins (made of oligomeric or polymeric proanthocyanidins), complex tannins (made of a catechin bound to a gallotannin or elagitannin), and phlorotannins (oligomers of phloroglucinol).
