Eupatilin (5,7-dihydroxy-3',4',6-trimethoxyflavone) is a flavonoid compound from Artemisia species that possesses beneficial biological activities such as anti-cancer, anti-oxidation, and anti-inflammatory activities. However, an anti-adipogenic effect has not yet been reported. In this study, we found that eupatilin significantly inhibited the adipogenesis of 3T3-L1 adipocytes. Eupatilin decreased intracellular lipid accumulation and suppressed the expression level of key adipogenic regulators in 3T3-L1 adipocytes, including peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT-enhancer-binding protein alpha (C/EBPα), in a concentration-dependent manner. These results show that eupatilin significantly inhibits 3T3-L1 cell differentiation and suggest that it has potential as a novel anti-obesity therapy.
