설명

일반 설명

Catechins are major flavonoids present in green tea accounting to 90%. (−)-catechin is comparatively less bioavailable than the (+)-catechin for intestinal absorption.

애플리케이션

(-)-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

생화학적/생리학적 작용

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.
