Aster yomena (AY) have been used as a traditional medicine to treat cough, bronchial asthma, and insect bites in Korea. In this study, we evaluated the inhibition of adipogenesis in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice by AY ethanol extract. Lipid accumulation measurement indicates that AY markedly inhibited adipogenesis in a dose-dependent manner. qRT-PCR results demonstrated that the mRNA expression of adipogenic transcription factors such as peroxisome proliferator-activated receptor-γ (PPAR-γ) in 3T3-L1 cells were significantly down-regulated by AY treatment. And inhibited the expression of FAS, a protein responsible for lipid synthesis, transport and storage. Oral administration of AY (100, 250, and 500 ㎎/㎏, P.O/daily for 4 weeks) was conducted in high-fat diet induced obese mice and C57BL/6 mice. AY was orally administered for 4 weeks to extract liver and epididymal fat, and hematoxylin and eosin staining(H&E staining) was observed. Observation showed that the fat concentration of liver tissue tended to decrease dose-dependently and decreased significantly at 500 ㎎/㎏ concentration. The AY-administered group of HFD-induced mice had a lower body weight gain, along with decreased triglycerides and total cholesterol compared with the control mice, however, the HDL-cholesterol/total cholesterol ratio was increased. These results indicate that AY exhibits anti-obesity effects in obese mice by decreasing in serum lipid levels and lipogenesis related gene.
