Curcumin and resveratrol show cytotoxicity in adipocytes only at relatively high concentrations. Adipocytes were cultured without or with the indicated concentrations of curcumin (●) or resveratrol (○) in complete media containing 10% fetal bovine serum for 24 h. Wst-1 reagent was then added to cultures to a final dilution of 1:10, cultures were incubated for an additional one hour and color was measured by spectroscopy (450 nm; reference wavelength, 690 nm).
