Preparation method of water-soluble curcumin polymer

The invention relates to the field of medicine synthesis, in particular to a preparation method of a water-soluble curcumin polymer. The method comprises the steps as follows: (1) material mixing; (2) acidification; (3) preparation of the polymer. The method is simple and convenient, the prepared curcumin polymer has outstanding thermal stability, storage stability, controllable molecular weight and controllable degradation rate, the prepared excellent water-soluble curcumin polymer can be applied to oxidation resistance, virus resistance, liver protection, choleresis, cancer resistance, blood lipid reduction, HIV resistance, bacteriostasis and the like, and compared with curcumin itself, the water-soluble curcumin polymer has the advantages that the stability and bioavailability of curcumin are greatly improved, the cytotoxicity and anticancer capacity of the curcumin for cancer cells are remarkably improved, and the water-soluble curcumin polymer is expected to be a novel anticancer medicine. 本发明涉及药物药物合成领域，
