Objectives : The purpose of this study is to evaluate the anti-lipogenic effect of Sobuncheong-eum on non-alcoholic fatty liver disease in free fatty acid induced cellular model.

Methods : HepG2 cells were treated with palmitate for 24h to overload intracellular triglyceride (TG) content in the presence or absence of Sobuncheong-eum extract.
After palmitate treatment, Intracellular TG content was measured with TG assay kit. Several lipogenesis related markers, including AMP-activated protein kinase (AMPK),
sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), and fatty acid synthase (FAS), were assessed using Western-blot analyses and RT-PCR.

Results : Palmitate markedly increased intracellular TG in HepG2 cells, and which were alleviated by coadministered Sobuncheong-eum extract.
Sobuncheong-eum extract activated AMPK, which plays a key role in reducing hepatic lipid accumulation, and reduced lipogenic fators, SREBP-1c, ACC, and FAS.

Conclusions : Taken together, it is conceivable that Sobuncheong-eum has an potential to alleviate steatosis, and which may be mediated by activating AMPK at least in part.
