Preparation of penta-O-galloyl-β-d-glucose from tannic acid and plasma pharmacokinetic analyses by liquid–liquid extraction and reverse-phase HPLC

The gallotannin penta-O-galloyl-beta-d-glucose (PGG) has many biological activities including in vivo anti-cancer efficacy. We present in this paper a scaled-up protocol for its preparation in high purity from tannic acid by acidic methanolysis with typical yield of 15%.
