cyanidin-3-o-beta-glucopyranoside and 3-aminobenzeneboronic-acid

Stabilizing mechanisms through covalent and non-covalent interactions have been studied along the years for color stabilization of anthocyanin dyes. In this work, the chemical functionalization of a natural and biocompatible marine-based polysaccharide (alginic acid) with 3-aminophenylboronic acid via carbodiimide coupling chemistry was carried out in order to create a bifunctional material for pH-dependent selective interaction with colored cyanidin-3-glucoside chemical species. The interaction studies were performed by UV-Vis,
