Abstract
Epicuticular wax from Juniperus scopulorum contains hydrocarbons (16%), esters (11%), free acids (1%), nonacosan-10-ol (27%), nonacosane-diols (7%) and estolides (16%). The major hydrocarbon is tritriacontane; the principal esters are C₃₄–C₄₆, mainly octyl and decyl esters of C₂₈-C₃₆ acids; and the diols consist of nonacosane-4,10-diol (57%),5,10-diol (28%), 7,10-diol (11%) and 10,13-diol (4%). Hydrolysis of the estolides gave a mixture of acids, ω-hydroxy acids, α, ω-diols, alcohols and hydroxy acids. The hydroxy acids are a new class of C28–C36 acids with the OH attached to either the eighteenth or twentieth carbon from the terminal methyl end; the major component is 13-hydroxydotriacontanoic acid. Syntheses of this acid and of nonacosane-4,10-dione and nonacosane-4,10-diol are described.
