초록

In this study, we investigated anti-obesity effect of isoegomaketone (IK) isolated from leaves extract of Perilla frutescens (L.) Britt. cv. We verified differentiation and lipid accumulation by Oil Red O staining in 3T3-L1 cells after IK treatment with differentiation media. IK inhibited mRNA expression of adipocyte specific genes that were related with differentiation of 3T3-L1 cells. We confirmed the effects of IK on body weight and visceral fat mass in obese mice. Mice were randomly divided into three groups; normal diet group (ND), high-fat diet group (HFD) and high-fat diet with IK group (HFD-IK). The obesity mice were induced by feeding the 45% high-fat diet to the C57BL/6J mice during 4 weeks. After HFD-IK was orally administered 10 mg/kg of IK. As a result, the body weight of HFD and HFD-IK was increased 2.4 times and 1.7 times of ND, respectively. Also visceral fat mass of HFD was increased 24 times but in the case of HFD-IK was increased to 13 times in comparison with ND. Taken together, our findings suggest that IK reduced differentiation and adiogenesis in 3T3-L1 cells, decreased the body weight and visceral fat mass in obesity mice. These results suggest that IK may have a potential benefit as anti-obesity material.
