Abstract
In this study, the anti-obesity activity of Smilax china methanol extract (SCME) was evaluated using a pancreatic lipase enzyme inhibition assay, and a cell culture model system. Results indicated that, SCME effectively inhibited pancreatic lipase enzyme activity in a dose-dependent manner. Furthermore, SCME significantly suppressed insulin, dexamethasone, 3-isobutyl-1-methylxanthine-induced adipocyte differentiation, lipid accumulation, and triglyceride contents on 3T3-L1 preadipocytes, in a dose-dependent manner. The anti-adipogenic effect was modulated by cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins (C/EBP) ${\alpha}$, $C/EBP{\beta}$, and the peroxisome proliferator-activated receptor ${\gamma}$ gene and protein expressions. Moreover, SCME triggered lipolysis effects dose-dependently on adipocyte. Taken together, these results provide an important new insight into SCME, indicating that it possesses anti-obesity activity through pancreatic lipase inhibition, anti-adipogenic and lipolysis effects. SCME may therefore be utilized as a promising source in the field of nutraceuticals. The identification of active compounds that confer the anti-obesity activities of SCME may be a logical next step.
