Beschreibung

Allgemeine Beschreibung

Catechin is produced by Cutch tree and is abundantly found in tea leaves, grape seeds, vegetables and plant-based beverages. It is a plant-derived, polyphenolic anti-oxidant and acts as a plant secondary metabolite.

Anwendung

(±)-Catechin hydrate has been used:

• to study its modulatory effect on drug resistance in human ovarian cancer cells
• to construct the standard curve of total flavonoid content
• to study its effects on the physiological parameters of Solanum lycopersicum

Biochem./physiol. Wirkung

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.
