摘要:
The present invention relates to the preparation of a Cynara scolymus extract obtainable by fractioning on a resin. The process of the invention allows to obtain an extract, starting from the aerial parts of the plant Cynara scolymus, containing three classes of active principles, namely dicaffeoylquinic acids, luteolin and cynaropicrin glycosides, in a constant ratio. Cynaropicrin is stabilized by addition of precise amounts of sulfated amino acids or suitable thio-derivatives. These extracts have hypolipemizing, anti-dyspeptic and vascular anti-inflammatory activities. The extracts are mainly formulated in Enothera biennis oil or in oils rich in ω-3 and ω-6 acids which enhance the vascular activity.

The present invention relates to a polysaccharide of Echinacea angustifolia roots, having molecular weight of 1.3 x 10 Da and consisting of rhamnose, arabinose, galactose and galacturonic acid in ratio 0.5:2.5:1.75:10.25. The polysaccharide is recovered from spontaneous or cultivated Echinacea angustifolia roots by means of a process comprising 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.
