Abstract: The present invention relates to an extract of Salix spp obtainable by fractioning on a resin and to the process for its preparation. The extract of the invention is characterized by an high content in salicin derivatives, reduced content in high molecular tannins and a content in proanthocyanidins sufficient to inhibit some tissue metal proteases. The product is formulated in oils rich in ?-3 and ?-6 acids which provide a better absorption of the extract active principles, also increasing synergetically their action.

Abstract: A process for the extraction of Vitis vinifera seeds which comprises: a) extraction of grape seeds with a solvent (total extract); b) removal of water-insoluble tannins; c) optional removal of water-soluble tannins; d separation of the products with different MW, through chromatographic purification on a column.

Abstract: The present invention relates to the use of extracts of plants or roots of the Paeonia genus, in particular Paeonia lactiflora, for the preparation of growth promoters for use in livestock.

Abstract: An Echinacea angustifolia extract 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 Echinacea angustifolia. The extract can be used for the treatment of pathological conditions in which it is desirable to strengthen the immune defenses.

Abstract: A polysaccharide of Echinacea angustifolia roots, having molecular weight of 1.3×105 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 Echinacea angustifolia 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.
