Chemical Properties:
  1. Gallocatechin gallat in tea are mainly phenotypic catechins, namely epigallocatechin gallate EGCG, epigallocatechin EGC, epicatechin gallate ECG, epicatechin EC, they account for approximately 60~80% of the total catechins. Among them, EGCG is the substance with the highest content of polyphenols in green tea, and it is also recognized as the most important antioxidant component in tea.
  2. However, existing studies have confirmed that phenotypic catechin isomers such as gallocatechin gallate GCG exhibit strong physiological activities in certain aspects, such as antioxidant and scavenging activities from Chemicalbook.
  3. Gallocatechin gallat catechin monomer compounds are mainly extracted from tea leaves or tea extracts. Commonly used methods of separation and purification include liquid-liquid extraction, column chromatography, medium and low pressure column chromatography, high-pressure preparative liquid chromatography and high-speed countercurrent chromatography. There are no lack of other methods for the separation and purification of catechins, and two or more methods are often used in combination. There are common reports on the separation and purification of epigallocatechin gallate EGCG, epicatechin gallate ECG, etc. in the literature and patents, but there are few methods for preparing gallocatechin gallate GCG monomer compounds.
  1. Gallocatechin gallat view of the good nutritional health and physiological and pharmacological effects of gallocatechin gallate GCG, in the quality control of tea and tea-related products, the optimization of the production process and the research process of its basic efficacy, it is necessary for Chemicalbook to require high-purity gallbladder The GCG monomer compound of theophyllin gallate. Biological activity (-)-Gallocatechingallate is a polyphenolic substance in tea, which has anti-cancer effects.
