摘要：
The present invention relates to a polysaccharide of Echinacea angustifoliaroots, having molecular weight of 1.3 x 105 Da and consisting of rhamnose,arabinose, galactose and galacturonic acid in ratio 0.5:2.5:1.75:10.25. Thepolysaccharide is recovered from spontaneous or cultivated Echinaceaangustifolia roots by means of a process comprising the following steps: a)depriving the roots of non polysaccharidic constituents by extraction withsolvent； b) extracting the polysaccharidic fraction from the roots as directlyobtained from the preceding step； c) isolating the polysaccharide bychromatography of the polysaccharidic fraction. Due to its immune-stimulatingproperties, the polysaccharide can be used for the preparation of medicaments,food supplements' or nutraceutical compositions to administer whenever it isdesirable to strenghthen the immune system body defenses.
