Abstract

There are many kinds of active components in tea. Among them, methylated catechin has the functions of anticancer, antimutagenic, antitumor, anti-inflammatory, antiviral, scavenging free radicals and antioxidation. This paper mainly introduces the research and design of egcg3me in clinical medical extracted tea based on Internet of things technology. In this paper, through the overview of medical Internet of things and the analysis of extraction methods of methylated catechin, the production process of traditional tea polyphenol extraction and methylated catechin purification was improved. Methylated catechin was purified by resin purification method and catechin monomer was separated and prepared. The tea powder was used as raw material, and the high purity methylated catechin was obtained by crystallization with macroporous adsorption resin Tea element monomer. In this paper, the effects of various factors on the extraction of tea polyphenols and the purification of methylated catechins were studied. The experimental results showed that the best adsorption effect of catechin was obtained when the adsorption flow rate was 1BV / h; when the elution flow rate was 2BV / h and the elution volume was 4-5 BV, the volume and concentration of catechin in unit volume were the largest. In terms of crystallization, when the concentration of solution is 30%, the crystallization time is 4 days, and the crystallization temperature is 4 ℃, the effect of catechin is the best. It can be seen from the above results that the new technology of tea polyphenol extraction and methylated catechin purification has the advantages of simple process, short production cycle, low cost and high yield, which has a good development prospect.
