ABSTRACT:
A method for simultaneous preparation of ergosterol and ubiquinone-9 in a single process, characterized in that a biolipid fraction, isolated from a biomass of yeast, for example Candida, is used in the process.
This fraction is hydrolyzed with a solution of alkali in alcohol, and unsaponifiable components are then extracted. The extract is evaporated to precipitate ergosterol, while the mother liquor is passed through a chromatographic column to isolate ubiquinone-9. According to the invention, both end products are obtained in a single process.
