Composition of the Epicuticular Wax Esters of Picea abies (L.) Karst.

Abstract

The long-chain alkyl esters homologues of the cuticular needle wax of Picea abies consist of a series of isomers, which are formed by different n-fatty acids and n-alkanols of various chain lengths. Even-numbered esters are dominating. Methyl esters range from C27 to C37, even-numbered esters are only minor components. Furthermore, a new class of homologue wax esters was isolated. Examination by gas chromatography, mass spectroscopy and chemical studies resulted in identification of pentenyl esters of triacontanoic, dotriacontanoic, tetra-triacontanoic and hexatriacontanoic acid. © 1995, Verlag der Zeitschrift für Naturforschung.
