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.

The effect of C-18 silica gel surface coverage on the retention behaviour of some estrone derivatives in reversed phase high performance liquid chromatography has been studied. Two commercial columns with different C-18 coverage, Spherisorb ODS-1(8 % carbon content) and Li Chrosorb RP-18(22% carbon content), using methanol-water as the eluent, were used.
