Solubility of curcuminoids in FCS. A) Total curcuminoid solubility (μM) in 1 ml of FCS as a function of adding increasing amounts (1–70 mg) of solid curcuminoids. B) Curcuminoid solubility (μM) in 1 ml of FCS as a function of adding 10 μl aliquots of DMSO-dissolved curcuminoids at concentrations ranging from 10 to 500 mM.
