Solubility of curcuminoids in BSA solutions. A) Curcuminoid solubility (μM) in 1 ml of 5% BSA as a function of adding increasing amounts (1–70 mg) of solid curcumin. B) Curcuminoid solubility (μM) in 1 ml of 5% BSA as a function of adding 10 μl aliquots of DMSO-dissolved curcuminoids at concentrations ranging from 10 to 500 mM. C) Curcuminoid solubility (μM) as a function of adding 30 mg solid curcuminoids to 1 ml of BSA solutions ranging in concentrations from 0.2 to 10%. D) Curcuminoid solubility (μM) as a function of adding 10 μl aliquots 500 mM DMSO-solubilized curcuminoids to 1 ml of BSA solutions ranging in concentrations from 0.2 to 20%.
