Process for the preparation of extracts having high content in anthocyanosides |
| abstract |
A process for the preparation of extracts with high content in anthocyanosides consists in treating plants, parts of plants or crude extracts with bisulfate ions to give anthocyanoside-bisulfate 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. |
