Acid Esters

Synthetic and naturally occurring mixtures of fatty acid esters of cholesterol and plant sterols were separated by gas chromatography under the conditions previously described for triglyceride fractionation. The separations obtained were based primarily on the molecular weight or carbon number of the material, a difference of one methylene unit either in the fatty acid or the sterol side chain being usually sufficient for a complete resolution. Under isothermal conditions, however, partial separations could also be brought about between certain esters differing only in the unsaturation of the fatty acid moiety. Using weighed mixtures of synthetic steryl esters proportionally correct quantitative recoveries were demonstrated for both cholesterol and plant sterol esters of the common fatty acids.

The phase transitions and effective optical rotary power of saturated and monounsaturated aliphatic esters of cholesterol with 18 and 22 carbon atoms in the chain have been described. The effect of cis/trans isomerism on these properties is discussed.

Long Chain

The long chain polyprenols composed of 30 and more isoprene units from leaves of plants belonging to the genera Potentilla and Rosa have been described. They occur in the form of fatty acid esters. The composition of polyprenol mixture was species dependent and its content reached ca. 0.5% wet weight. Large scale preparation of individual polyprenols from a natural polyprenol mixture was performed using time-extended liquid chromatography on the hydrophobic gel Lipidex-5000.Key words: long chain polyprenols, Rosaceae.
