Abstract

Abstract Pinus thunbergii is a black pine that has been widely used in health-promoting foods. This study was conducted to investigate the hepatoprotective effects of the alcohol-aqueous extract of Pinus thunbergii PARL leaves (PTE) in ethanol-induced liver-damaged mice. PTE increased the weight and survival rate of mice while reducing the levels of serum hepatic marker enzymes. PTE also restored the levels of antioxidant enzymes in liver tissues while drastically increasing lipid peroxidation concentrations. Histopathological examination of PTE-treated mice presented relatively less lipid droplets and hepatic tissue damage compared to ethanol-treated mice. Finally, to identify PTE components, Natural Products Application Solution with UNIFI along with an in-house library was processed and results revealed 35 compounds in the extract. These compounds were reported to exhibit significant antioxidant and/or hepatoprotective properties. Our results suggest that PTE improves liver function and can be developed as a food product with hepatoprotective effects.
