Abstract: | The major components (50%) of the surface lipid extract of fungal spores (5.6% of dry spore wt) of Sphaerotheca fuliginea are esters of primary alcohols and fatty acids. Esters (15%) of primary alcohols and a Δ2t acid are present. The major acid moieties of the alkyl esters are C22 and C24 and of the Δ2t alkyl ester is Δ2t C22; for both classes eicosanol is the major primary alcohol. The major ester of each class was concluded to be eicosanyl docosanoate and eicosanyl trans-2-docosenoate. Minor components are saturated and Δ2t methyl and diol diesters and free fatty acids. The major acid moieties of the diol diesters are C22 and C24 and the major diol is 1,12-dodecanediol. |
