Structure of gentiodelphin is determined to be 5,3'-di-O-(6-O-trans-caffeoyl-β-D-glucosyl)-3-O-(β-Dglucosyl)delphinidin.The anthocyanin is stable in dilute neutral aqueous solution.This stabilization may be caused from intramolecular hydrophobic interactions among the aromatic nuclei; the anthocyanidin being sandwiched in between two caffeic acids.
