| titleOfInvention | A kind of method extracting monomer EGCG from fresh tea leaf in its |
| abstract | The invention discloses a kind of method extracting monomer EGCG from fresh tea leaf in its, belong to natural product chemistry technical field, specifically comprise the following steps: S1. soaks; S2. centrifugal; S3. primary sorption; S4.MVR concentrates; S5.CF filters; S6. second adsorption; S7. concentrate; S8. rinsing; S9. dewater; S10 is dry; S11. deironing.The present invention adopts fresh tea leaf in its to be raw material, easy gelatinization when overcoming in traditional technology at high temperature lixiviate after adopting stem tea to pulverize and sieve, the shortcoming of not easily filtering, do medium with purified water and directly isolate EGCG monomer, decrease the leaching of some fat-soluble agricultural chemicals, in purifying process, adopt LX-8 resin absorption EGCG, HZ818 resin absorption caffeine, crystallization, rinsing, drying obtain EGCG monomer, product off-white color is to white powder, and content reaches about 99%.This method have simple to operate, separation efficiency is high, cost is low, with short production cycle, the advantage that the product purity of production is high, is applicable to batch production scale operation. |
