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.

Long Chain

The presence of poly-cis-prenols of chain length 20-60 isoprene units or longer in leaves of plants belonging to Combretaceae family was shown to be a common feature in this group of plants. The polyprenols of this type were found in half of the 20 species studied. In most cases the polyprenols occurred in the form of fatty acid esters. Only in one species--Combretum molle, the polyprenols were found in the form of free alcohols. The amount of long-chain polyprenols varied with the plant species; the richest source was C. molle (about 4% of dry mass of leaves). Polyprenol groups characteristic of other systematic families of plants were not found in the Combretaceae studied.
