Protective Effect of Korean Medicinal Plants on Ethanol-Induced Cytotoxicity in HepG2 Cells

초록

The purpose of this study is to evaluate cytoprotective effect of Korean medicinal plants on alcohol-induced cytotoxicity in liver cells. Out of the 120 plant extracts tested in this study, 53 plant extracts enhanced alcohol-induced cytotoxicity in liver cells by 50~80%, while other 11 plant extracts including Crataegus pinnatifida reduced cytotoxicity by 1~68%. The results of DPPH free radical test and LDL lipid peroxidation test on the plant extracts that sharply reduced cytotoxicity in liver cells shows that Crataegus pinnatifida and Cinnamomum cassia had antioxidative effect. This study reports that the plant extracts that enhance or reduce ethanol-induced cytotoxicity in liver cells can be research objects as cytotoxic plants or cytotoxicity-protective plants.
