Poly[3-(3,4-dihydroxyphenyl)glyceric acid] from Anchusa italica roots

Abstract:

Elucidation of the main structural unit of a water-soluble, high-molecular weight preparation from the crude polysaccharides of Anchusa italica Retz. roots has been carried out. According to 13C NMR, 1H NMR and 2D heteronuclear 1H/13C HSQC spectral data, the main structural element of the high-molecular, water-soluble preparation was a regularly substituted polyoxyethylene chain, namely poly[oxy-1-carboxy-2-(3,4- dihydroxyphenyl)ethylene]. Most carboxylic groups of this caffeic acid-derived polymer of A. italica are methylated.
