The characteristics of the solubility of stigmasterol and b-sitosterol in a solvent of cyclohexanone or n-pentanol at different temperatures and the phase diagram of stigmasterol /b-sitosterol / cyclohexanone (or n-pentanol) under room temperature were determined. The experimental results show that the solubility of b-sitosterol in n-pentanol or cyclohexanone is larger than that of stigmasterol in the same solvent at the same condition, and that the solubility of b-sitosterol increases much faster with temperature in cyclohexanone than that of stigmasterol. The recrystallization for separating and purifying stigmasterol and b-sitosterol from phytosterol using n-pentanol or cyclohexanone as a solvent was studied. The content of stigmasterol and b-sitosterol in the crystal product was analyzed by IR and UV spectra motheds.
