Abstract

This study investigated the antioxidant and hepatoprotective effects of Ainsliaea acerifolia water extract (AAWE) on HepG2 cells. Five types of caffeoylquinic acid (CQA) were detected in AAWE, namely, 4,5-di-O-caffeoylquinic acid (4,5-DCQA; 11.16 mg/g), 3,4-di-O-caffeoylquinic acid (3,4-DCQA; 5.23 mg/g), 5-O-caffeoylquinic acid (5-CQA; 4.88 mg/g), 3,5-di-O-caffeoylquinic acid (3,5-DCQA; 3.51 mg/g), and 4-O-caffeoylquinic acid (4-CQA; 3.31 mg/g). AAWE exerted ABTS+ antioxidant effects, evidenced by polyphenol content and 2,2'2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH radical scavenging) activities. AAWE (300 μ g/mL) treatment significantly decreased the activities of gamma glutamyl transferase (GGT), aspartate transaminase (AST), and lactate dehydrogenase (LDH) as compared to control and exerted protective effects against the increase in liver function index induced by lipopolysaccharide (LPS)/galactosamine (D-GalN) in HepG2 cells. In addition, the secretion of tumor necrosis factor (TNF)- α by HepG2 cells induced by LPS/D-GalN significantly increased in all treatment groups compared to that in the control. However, AAWE (100-300 μ g/mL) treatment significantly decreased the secretion of TNF- α compared to that in the control. These results suggest that AAWE treatment reduces hepatotoxicity by increasing antioxidant activities, reducing GGT, AST, and LDH activities, and inhibiting TNF- α secretion.
