This study was carried out to investigate the effects of Salvia plebeia R. Br. ethanolic extract with differentaspects (stem/leaf and whole plant) on differentiation and lipid accumulation in 3T3-L1 preadipocytes. The morphologicalchanges and the degrees of lipid accumulation in 3T3-L1 cells were measured by Oil Red O staining and intra-cellular trig-lyceride (TG) assay. The mRNA expressions of special peroxisome proliferation activated receptor- genes (PPAR), CCAAT/enhancer-binding protein (C/EBPα), fatty acid synthase (FAS) and lipoprotein lipase (LPL) were detected by reverse tran-scriptase polymerase chain reaction (RT-PCR). The 50% ethanolic extracts (100μg/mL) of stem and leaf (SALE) and 30%ethanolic extracts (100g/mL) of whole plant (SAE) from Salvia plebeia R. Br. were significantly attenuated lipid accumula-tion during adipogenesis in 3T3-L1 cells. Ethyl acetate-soluble fractions (50μg/mL) significantly inhibited lipid dropletaccumulation in 3T3-L1 cells. In addition, SALE induced down-regulation of specific adipogenic transcriptional factors (C/EBPα and PPARγ) and target genes (FAS and LPL) during adipogenesis. Salvia plebeia R. Br. may be used as a safe and effi-cient natural substance to manage obesity.
