Abstract:

The potential hepatoprotective effects of five polyphenols, such as tea polyphenol, gallic acid, quercetin, kaempferol, apigenin and α-tocopherol (as a control) against oxidation damages of human hepatocyte induced by hydrogen peroxide or carbon tetrachloride were evaluated. The results showed that pre-treatment of hepatocytes with polyphenols at concentrations of 5, 10 and 20 mg/L for 1 h not only improve cell viability and the content of GSH, but also reduce LDH leakage and the formation of MDA in cells. The hepatoprotective effects of polyphenol compounds decrease in the following order: gallic acid > quercetin > tea polyphenol > apigenin > α-tocopherol > kaempferol. The protective mechanism may be associated with the high free radicalscavenging activity of polyphenlos.

Key words: polyphenol compounds, hepatocyte, induced damage, hydrogen peroxide, carbon tetrachloride
