General description

Epicatechin is a flavanol, that belongs to the class of secondary, polyphenolic plant metabolites.

Application

(-)-Epicatechin has been used:
  • to examine its biological effects in cell lines from human gender-specific cancers
  • to study its antiviral activity
  • to test its ability to regenerate this enzymatic activity both in vitro at the isolated MPO−H2O2−Cl- system and ex vivo in human polymorphonuclear leukocytes (PMNs)

Biochem/physiol Actions

This antioxidant is found in chocolate. (-)-Epicatechin is linked with cardiovascular effects. It is considered as a dependable standard due to its availability in cacao seeds and cocoa products. The halogenating activity of myeloperoxidase can be restored by (-)-epicatechin.
