The isolation and purification of a mixture of cis-trans-polyprenols from the leaves of Aesculus hippocastanum (horse chestnut) are described. Results of studies involving mass spectrometry, nuclear magnetic resonance, infrared spectroscopy, micro-hydrogenation and ozonolytic degradation show the mixture to be made up of undecaprenol, dodecaprenol and tridecaprenol with dodecaprenol predominating. Each of the prenols contains three trans internal isoprene residues and a cis ;OH-terminal' isoprene residue. They differ from each other only in the number of cis internal isoprene residues. The trivial names castaprenol-11, castaprenol-12 and castaprenol-13 are proposed to describe these compounds. Gas-liquid-chromatographic and reversed-phase partition thin-layer chromatographic evidence suggest the presence in the mixture of small quantities of castaprenol-10 also.
本文描述了从欧洲七叶树（马栗）叶子中分离和纯化顺反聚戊烯醇混合物的过程。涉及质谱分析、核磁共振、红外光谱、微氢化和臭氧分解降解的研究结果表明，该混合物由十一碳烯醇、十二碳烯醇和十三碳烯醇组成，其中十二碳烯醇占主导。每种聚戊烯醇都含有三个反式内部异戊二烯残基和一个顺式“羟基末端”异戊二烯残基。它们彼此之间的区别仅在于顺式内部异戊二烯残基的数量。为描述这些化合物，提出了俗名七叶树聚戊烯醇-11、七叶树聚戊烯醇-12和七叶树聚戊烯醇-13。气液色谱和反相分配薄层色谱证据表明，混合物中也存在少量的七叶树聚戊烯醇-10。
