Objective: To determine the equilibrium solubility of capsaicin in various medium. Method: To determine the solubility of capsaicin in physiological saline
oleic acid
isopropyl myristate
different concentration of ethanol
ethanol-phosphate buffer solution and polyethylene glycol 400 by HPLC. Result: The solubility of capsaicin increases with the decreasing polarity of solvent and the increasing percentage of semi-polarity solvent.When the concentration of ethanol was 40%
the solubility of capsaicin increased to 30.4 g ·L-1. Conclusion: The equilibrium solubility of capsaicin depends on the polarity of the medium.We can regulate the polarity of the medium to increase the solubility of capsaicin.
