Verwenden
(-)-Epicatechin gallate is polyphenols which are abundant in green and black teas. (-)-Epicatechin gallate (ECG) is a natural catechin with a single galloyl group. The hydroxyl groups of ECG contribute to its potent antioxidant activity and facilitate the killing of methicillin-resistant strains of S. aureus.
Definition
ChEBI: A gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of epicatechin. A natural product found in Parapiptadenia rigida.
Allgemeine Beschreibung
()-Epicatechin gallate is one of the major polyphenols present in green tea. It belongs to the catechin gallates group of organic compounds. ECG has a chemical structure like that of ()-epigallocatechin gallate (EGCG), the other major polyphenol found in green tea.
