TITLE PROCESS FOR SEPARATING STIGMASTEROL-DERIVED PRODUCTS (II) ABSTRACT OF THE DISCLOSURE This invention relates to the separation of crude mixtures of sterols, and more particularly it relates to the removal of stigmasterol derived products from crude mixtures of sterols. The present invention relates more specifically to a process for separating stigmasterol-derived products from phytosterol materials containing mixtures of stigmasterol, sitosterol and campesterol. These mixtures are reacted to form the corresponding .DELTA.4-3-keto derivatives of phytosterols. The .DELTA.4-3-keto derivatives of phytosterols are reacted by ozonolysis to form the 4-stigmasten-3-one-derived aldehyde material, 3- ketodinor-4-cholen-22-aldehyde, which can be isolated from the other .DELTA.4-3-keto derivatives of phytosterol by either chromatography or by treatment with sodium bisulfite and extraction with a suitable organic solvent much as toluene.
