Abstract: From the aqueous-ethanolic antipsoriatic mahonia extract a mixture of low-molecular-mass polysaccharides was isolated by ethanol precipitation of the undialyzable portion. They were composed of neutral sugar components with dominating glucose. Ion-exchange and gel-permeation chromatography was employed to obtain the dominant polysaccharide component which was proved by methylation analysis and NMR spectrometric measurements to be a linear(1→4)-β-D-glucan.
