Chrysanthemum zawadskii, a herbaceous perennial plant belonging to the Compositae, grows wild in Asian countries, including Japan, China, and Korea. The biological, antioxidative, anti-inflammatory, and antibacterial activities of C. zawadskii have been reported, its antiobesity activity has not been elucidated. In the present study, the effect of C. zawadskii methanol extract (CZME) on pancreatic lipase enzyme activity, adipocyte differentiation, and adipogenesis was investigated using an in vitro assay and a cell model system. CZME effectively suppressed lipase enzyme activity in a dose-dependent manner. CZME also inhibited insulin, dexamethasone, 3-isobutyl-1-methylxanthine (MDI)-induced adipocyte differentiation, lipid accumulation, and the level of triglyceride in 3T3-L1 preadipocytes in a dose-dependent manner, without cytotoxicity. The antiobesity effect of CZME might be modulated by gene and protein expression of cytidine-cytidine-adenosine-adenosine-thymidine (CCAAT)/enhancer binding proteins (C/EBP) α, C/EBPβ, and the peroxisome proliferator-activated receptor γ (PPAR γ). CZME also triggered lipolysis in a dose-dependent manner in MDI-induced 3T3-L1 preadipocytes. Taken together, these results provide important new insights into the antiobesity activities of C. zawadskii, showing that they involve pancreatic lipase inhibition, as well as antiadipogenic and lipolysis effects. CZME might be a promising source in the field of nutraceuticals. However, the active compounds that confer the antiobesity activities of CZME need to be identified.
