(-)-CATECHIN HYDRATE Usage And Synthesis

Uses

A natural phenol antioxidant plant secondary metabolite.

Uses

In dyeing and tanning.

Uses

(-)-Catechin has been used:

• to test its binding affinity towards estrogen receptor
• as a reference standard in high-performance liquid chromatography for quantification of polyphenols from plant extracts (HPLC)
• as a reference standard in kinetic studies to quantify antioxidants from Iranian green tea leaves

Definition

ChEBI: (-)-catechin is the (-)-enantiomer of catechin. It has a role as a metabolite. It is an enantiomer of a (+)-catechin.

General Description

This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG

Biochem/physiol Actions

Catechins have wide biological functionality. They induce antiviral and anticancer activities. Catechins also play a key role in regulating carbohydrate and lipid metabolism. It prevents fat accumulation.
