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.

Detection And Separation

The wood of the showy mountain ash was found to contain about 3% acetone-soluble material. The major constituents of the extract were a polymorphous xyloside of (+)-di-methoxyisolariciresinol, the recently discovered hydroxy diphenyls aucuparin and methoxyaucuparin, and fatty acid esters of β-sitosterol, another phytosterol, and of untractable phenolic material. Small amounts of free β-sitosterol and a mixture of hydrocarbons as well as traces of an unknown leucoanthocyanidin were also isolated. The xyloside predominated in the sapwood, whereas the aucuparins were found mainly in the heartwood. Gas–liquid chromatography was instrumental in the detection and separation of the aucuparins.
