Abstract
From the aqueous-ethanolic antipsoriatic mahonia extract a mixture of low-m olecular-mass polysaccharides was isolated by ethanol precipitation of the undialyzable portion. They were composed of neutral sugar components with d ominating glucose. Ion-exchange and gel-permeation chromatography was emplo yed to obtain the dominant polysaccharide component which was proved by met hylation analysis and NMR spectrometric measurements to be a linear (1 -->4 )-beta -D-glucan.
