By thin-layer chromatography on silica gel containing 20% of Supercel the following sterols have been isolated from a mixture of the sterols of the yeastCandida guilliermondii and identified: 5α-ergost-7-en-3β-ol, ergosterol, β-sitosterol, 4α-methylzymosterol, and 14α-demethyllanosterol. The amount of ergosterol in the mixture was 96%.
