A process for the extraction ofseeds which comprises:

Grape seeds extracts obtainable by fractioning on a resin

Anextract and a process for the preparation thereof are herein described. The extract is characterized by an alkylamides content lower than 0.1%, an echinacoside content ranging from 1 to 10% and containing from 1 to 15% of a polysaccharide characteristic of. The extract can be used for the treatment of pathological conditions in which it is desirable to strengthen the immune defenses.

Echinacea angustifolia extracts

A polysaccharide of roots, having molecular weight of 1.3&times;10 Da and including rhamnose, arabinose, galactose and galacturonic acid in ratio 0.5:2.5:1.75:10.25, is recovered from spontaneous or cultivated roots by means process including the following steps: a) depriving the roots of non polysaccharidic constituents by extraction with solvent; b)extracting the polysaccharidic fraction from the roots as directly obtained from the preceding step; c) isolating the polysaccharide by chromatography of the polysaccharidic fraction. Due to its immune-stimulating properties, the polysaccharide can be used for the preparation of medicaments, food supplements or nutraceutical compositions to administer whenever it is desirable to strenghthen the immune system body defenses.
