摘要

The compositions of esters containing unsaturated acyl moieties (triglycerides, steryl esters and terpenol esters) in A. palmeri, as determined by capillary gas chromatography/mass spectroscopy (GC/MS) analysis, are presented. In addition, the freefatty acid, sterol and triterpenol components were characterized. The triglycerides constituted the major class of esters. The major hydroxylated constituents were palmitic, linoleic and oleic acids and the sterol chondrillasterol. The sterols campesterol, stigmasterol, ergost-7-en-3beta-ol, chondrillast-7-enol and 24-ethylidenecholest-7-en-3beta-ol, and the triterpenols beta- and alpha-amyrin, lupeol, cycloartenol and 24-methylenecycloartenol were present in lesser quantities.
