    Cymbopogon citratus , commonly know as lemongrass, prossesses strong antioxidant, anti-tumor and anti-inflammatory properties. Howerver, its anti‑obesity activity remains to be elucidated. This study investigated the effect of ethanol extract of Cymbopogon citratus on adipogenesis, and its underlying mechanism, in 3T3-L1 preadipocytes. The results demonstrated that ethanol extracts of Cymbopogon citratus effectively suppressed intercellular lipid accumulation at non-toxic concentrations, and was associated with the down-regulation of adipocyte-specific transcription factors, including C/EBPα and PPARγ, and phosphorylation of AMPKα. Furthermore, ethanol extracts of Cymbopogon citratus increased p21 and p21 expression, while the expression of CDK2, cyclin A and cyclin B1 was reduced. As a result, ethanol extracts of Cymbopogon citratus seems to induce G0/G1 cell cycle arrest of 3T3-L1 cells. On the other hand, ERK and Akt signaling pathways were not involved in anti-adipogenesis by ethanol extracts of Cymbopogon citratus . Taken together, theses results suggest that ethanol extracts of Cymbopogon citratus inhibits adipocyte differentiation in 3T3-L1 cells and can be used as a safe and efficient natural substance to manage anti-obesity.
