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.
