title: The occurrence and seasonal distribution of C50-C60-polyprenols and of C100-and similar long-chain polyprenols in leaves of plants.
abstract: Large amounts of fully unsaturated, mainly-cis, higher isoprenoid alcohols consisting of 17-30 isoprene units were found in several plants of the Rosaceae family. They occur as mixtures of several prenologues with either C85 - or C100 - prenol dominating in the form of acetates. The highest level of these polyprenols (0.5-1.0% of wet weight) were found in Crataegus crus- galli , Cotonoaster lucida, Prunus serotina and Sorbus suecica (intermedia). Their content increased with increasing age of the leaves. The dynamics of this rise is different from that observed in the case of accumulation of free C50- C60 - prenols (up to 0.5% of wet weight) in leaves of various plant species.
