Beta-penta-O-galloyl-glucose

Beta-penta-O-galloyl-glucose (β-PGG) is a polyphenol compound found in a variety of plants and has been studied for its potential pharmacological properties. It is a type of tannin, specifically a hydrolyzable tannin, and is composed of five gallic acid residues linked to a glucose molecule.

Chemical Structure

Chemical structure of Beta-penta-O-galloyl-glucose

The chemical structure of β-PGG consists of a central glucose molecule, to which five gallic acid residues are attached via ester bonds. This structure is responsible for its classification as a hydrolyzable tannin, as it can be broken down into its constituent parts by hydrolysis.

Sources

β-PGG is found in a variety of plant species, including certain types of oak and sumac. It is also found in the nutgalls produced by some species of gall wasp.

Pharmacological Properties

Research into the pharmacological properties of β-PGG has suggested that it may have potential as a therapeutic agent in a variety of contexts. Studies have indicated that it may have antioxidant, anti-inflammatory, antiviral, and anticancer properties, among others. However, further research is needed to fully understand these effects and their potential applications in medicine.
