| titleOfInvention | A kind of preparation method of EGCG |
| abstract | The invention discloses the preparation method of a kind of EGCG, the preparation method of described EGCG uses the tea polyphenol extract thing containing EGCG to be raw material, through raw material pre-treatment, dress post, upper prop, eluting, concentrating, crystallize and the step such as purification obtains powder high-load EGCG, its EGCG monomer mass mark is more than 99%.The invention have the benefit that and production process effectively prevent a large amount of toxic solvents of use, production process is more environmentally-friendly, and solvent treating capacity is little, and operation is simple, ester catechin EGCG and ECG that difficulty is separated, can accomplish disposably to separate, good separating effect, separation efficiency is high, purify thing content high, crystallization time is short, and product is the most oxidizable, and product color is good, purity is high. |
