ABSTRACT:
The present invention provides a method of separating ergosterol from a solution containing ergosterol in water-insoluble organic solvent, comprising supplying water to the solution and precipitating ergosterol. According to the method of the present invention, ergosterol crystals can be obtained at a high yield. Moreover, controlled water supply provides granular ergosterol aggregates exhibiting good solid-liquid separation character at a high yield.
