Solubilities of stigmasterol, sitosterol (containing about 5% of stigmasterol), and their acetates in twenty two kinds of organic solvent were compared at 20±0.1°C. The differences between the solubilities of stigmasterol and sitosterol were great in iso-butyl alcohol and n-amyl alcohol, and difference between the solubilities for the acetates was great in cyclohexanone. Stigmasterol was concentrated in higher yield by simpler operation by repeating iso-butyl alcohol and n-amyl alcohol extraction of soysterol than by ethylene dichloride-n-heptane.
