Palyphenol–anthocyanin copigmentation
Abstract
The complexation of natural polyphenols with malvin chloride has been examined; a model for the preferred mode of chelation of β-1,2,3,4,6-penta-O-galloyl-D-glucose (4) with various aromatic substrates (the ffavylium ion, caffeine, methylene blue, and daunomycin) is proposed.
