%X The separation and purification of b-sitosterol and stigmasterol from phytosterol by the crystallization method using n-pentanol and cyclohexanone as solvents were studied based on the difference of the solubilities of stigmasterol and b-sitosterol and the variation of solubility with temperature. The experimental results show that the content of b-sitosterol is more than 87% after the third fractional crystallization in cyclohexanone and the content of stigmasterol is more than 92% after the fifth crystallization in n-pentanol or cyclohexanone.
