Objectives : In this study, we investigated the biological activities such as anti-obesity using Samwondan ethanol extract (SWD). SWD is a complex with Salicornia herbacea Linnaeus, Saururus chinensis Baill and Houttuynia cordata Thunberg as the main raw material.Methods : The SWD was extracted 80% ethanol. 3T3-L1 preadipocytes were induced adipogenesis by differentiation media with SWD at 1 μg/mL, 10 μg/mL, and 100 μg/mL. Effect of SWD performed using MTT assay, oil red O staining (observation by microscope), and reverse transcription polymerase chain reaction. Also we measured production of triglyceride (TG), fatty acid, and acetyl-CoA carboxylase (ACC).Results : Non-cytotoxicity was in all test group from range of 1 μg/mL to 100 μg/mL on pre-adipocyte. The droplet and production of lipid were decreased significantly by the SWD. And TG was decreased by approximately 89%, 85% and 82%, upon the SWD treatment at concentration of 1 μg/mL, 10 μg/mL, and 100 μg/mL. Moreover, the SWD showed inhibitory effects on the expression of the C/EBP (CCAAT/enhaner binding protein)β, C/EBPα, and peroxisome proliferator-activated receptorγgenes in adipocytes. The SWD at 100 μg/mL concentration showed inhibitory effect on fatty acid production by 79%. Also ACC production were decreased dose-dependently.Conclusions : From the results above, we concluded that the SWD indicated significantly anti-obesity effects.
