Description générale

Catechin hydrate is a polyphenolic flavonoid that exhibits antioxidant properties. It is commonly found in green tea, grape seeds, and bark of few trees like acacia and mahogany.

Application

(+)-Catechin hydrate can be used:
  • As an inhibitor of steel corrosion in hydrochloric acid solution.
  • As a model compound in the study of antimicrobial activities of flavonoids on Escherichia coli.
  • As a starting material for the synthesis of catechin glucosides of biological importance.

In this study, the antioxidant activity and hepatoprotective effect of inulin and catechin grafted inulin (catechin-g-inulin) against carbon tetrachloride (CCl4)-induced acute liver injury were investigated. Results showed that both inulin and catechin-g-inulin had moderate scavenging activity on superoxide radical, hydroxyl
