| Hazard Information | Back Directory | [Uses]
(+/-)-Catechin xHydrate is an antioxidant flavonoid. | [Definition]
ChEBI: Catechin is members of the class of hydroxyflavan that have a flavan-3-ol skeleton and its substituted derivatives. | [Biological Activity]
Catechin has phytotoxic properties. Racemic catechin may be used in studies on seed germination and plant invasiveness. Catechin and Epigallocatechin gallate (EGCG) may be used with other polyphenol flavonoids to study their effects in oxidation and peroxidation-related processes.''Polyphenolic antioxidant. Used in traditional Chinese medicine. | [target]
