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.
在使君子科植物的叶片中，链长为20 - 60个异戊二烯单元或更长的多顺式聚戊烯醇的存在被证明是该类植物的一个共同特征。在所研究的20个物种中，有一半发现了这种类型的聚戊烯醇。在大多数情况下，聚戊烯醇以脂肪酸酯的形式存在。仅在一个物种——柔毛风车子（Combretum molle）中，聚戊烯醇以游离醇的形式存在。长链聚戊烯醇的含量因植物种类而异；最为丰富的来源是柔毛风车子（约占叶片干质量的4%）。在所研究的使君子科植物中未发现其他植物系统科特有的聚戊烯醇基团。
