Special attention was paid to the occurrence of dolichol in various tissues of different plants. Dolichols were found to occur in all of the tissues examined except for flowers of the rubber plant. The chain length distributions of dolichols in seeds, young roots, young shoots, young leaves and old leaves of the rubber plant were C70-C95, C85-C105, C80- C105, C75-C105and C65-C90, respectively. In the case of ginkgo, the chain length distributions of dolichols in seeds, embryos, young and old leaves were C70-C90, C70-C85, C70-C90and C80-C95, respectively. Pine seeds were found to contain dolichols with the chain length distribution of C70-C90. Two kinds of polyprenol families were detected in leaves of the rubber plant and ginkgo. The longer chain polyprenol family was also detected in seeds of the rubber plant, in seeds and embryos of ginkgo and in seeds of pine. The chain length distributions of the polyprenols were not necessarily the same as those of dolichols occurring in the same tissues.Mahidol UniversityAgricultural and Biological SciencesBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1016/S0031-9422(98)00581-0
