In this study, two polymethoxylflavones (PMFs), including nobiletin and tangeretin, and one flavonoid, hesperetin with one methoxyl group, were investigated to inhibit lipid accumulation using 3T3-L1 adipocytes. The reducing lipid droplets of the three compounds at 50 μM followed the order nobiletin=tangeretin>hesperetin; the inhibition of triglyceride levels was in the order nobiletin> tangeretin> hesperetin, indicating the numbers of methoxyl groups on the benzene ring play an important role in reducing lipid accumulation. These results imply polymethoxylflavones with high degree of methoxylation are easily permeable to cell membranes and demonstrate more regulating adipogenesis. The findings of this study are useful for designing new antiadipogenic agent and is therefore a potentially lipid lowering compounds based on chemical structure.
