Abstract
A process for the preparation of extracts with high content in anthocyanosides consists in treating plants, parts of plants or crude extracts with bisulfite ions to give anthocyanoside-bisulfite adducts. Said adducts are then eluted on non ionogenic resins at pH 5-6 and the obtained solution is extracted with polar organic solvents immiscible in water. The obtained extracts have a constant and standardized composition in anthocyanosides.
