Metabolically beneficial effects of decursin and decursinol angelate have been reported. However, it is unclear whether Angelica gigas Nakai extract (ACNE), which is rich in decursin and decursinol angelate, can alleviate high-fat diet (HFD)-mediated non-alcoholic fatty liver disease and dyslipidemia. In this study, c57BL6/J mice were fed a HFD, or HFD with various doses of ACNE for 16 weeks. Supplementation with AGNE attenuated glucose and insulin intolerance, hepatic steatosis and inflammation, and hypertriglyceridemia induced by the HFD. ACNE significantly suppressed hepatic de novo lipogenesis through activation of adenosine monophosphate-activated protein kinase (AMPK). HepG2 cells treated with free fatty acid mixture (oleate:palmitate = 2:1) displayed increases of de novo lipogenesis and consequent lipid droplet formation. Addition of decursin or decursinol angelate increased Sirtl expression, which suppressed lipid accumulation in HepG2 cells. These results indicate that the metabolic effects of AGNE may be related to the induction of Sirtl and consequent activation of AMPK.
