Abstract

The main features of the structure of the pectic acid from the racemes of German chanomile have been established. The main polysaccharide chain consists of D-galacturonic acid residues in the pyranose form with α-1→4 bonds. Isolated single-unit branches of the neutral monosaccharides galactose, arabinose, and xylose are possible. L-rhamnose, which was isolated from the degradation products of the permethylated pectic acid only in the form of 3,4-di-O-methyl-L-rhamnose is apparently included in the main polysaccharide chain.
