THE DIVERSITY OF POLYPRENOL PATTERN IN LEAVES OF FRUIT-TREES BELONGING TO ROSACEAE AND CORNACEAE

The polyprenol pattern in leaves of fruit trees belonging to the Rosac eae (genera: Prunus, Malus) and Cornaceae (genus: Cornus) families is presented. The content of polyprenyl acetates varied within plant spec ies between 10-50 mg per gram of dry weight. In genus Prunus, Cornus a nd in representatives of species Malus domestica, a mixture of polypre nols composed of 18, 19, 20, 21 isoprene units was found. In six speci es of genus Prunus (sour-cherry): P. serrulata-spontanea, P. yedoensis , P. fruticosa. P. kurilensis, P. subhirtella and P. incisa the presen ce of a second polyprenol family, i.e, the group of prenologues consis ting of prenol -35, -36, -37, etc. up to -42 was detected.
