METHOD FOR THE PREPARATION AND USE OF AN ENRICHED CYANIDINE-S-O-BETA-GLUCOPYRANOSIDE EXTRACT AND DERIVATIVES THEREOF FROM FRUITS AND VEGETABLES CONTAINING SAID ANTHOCIANIN AND METHOD FOR THE PURIFICATION AND USE OF CYANIDINE-3-O-BETA- GLUCOPYRANOSIDE

摘要

The present invention concerns a method for the preparation and the use of an extract enriched of cyanidin-3-O-ß-glucopyranoside and of its derivatives obtained from fruits or vegetables containing the aforementioned anthocyanin, and for the purification and the use of cyanidin-3-O-ß-glucopyranoside and of its derivatives from this extract. The extract enriched of cyanidin-3-O-ß-glucopyranosideand of its malonylated cyanidin-3-O-ß-glucopyranoside derivative, free of any toxic compound, can be used as a dietary supplement (nutraceutical), whilst the cyanidin-3-O-ß-glucopyranoside and its malonylated cyanidin-3-O-ß- glucopyranoside derivative can be obtained at a purity degree suitable for the preparation of pharmaceutical products.
