Lipophilic Components from the Ecuadorian Plant Schistocarpha eupatorioides

Phytochemical investigation of secondary metabolites of the Ecuadorian plant Schistocarpha eupatorioides (Fenzl) Kuntze (Asteraceae) afforded three phytyl fatty acid esters along with a mixture of unidentified polyprenols, the very well known sterols beta-sitosterol and stigmasterol, and their corresponding fatty acid esters and glucosyl derivatives. The structures of the compounds were elucidated on the basis of various spectroscopic means. In addition, a volatile fraction was separated the composition of which, comprising sesquiterpene hydrocarbons as the main fraction, was determined by GC-MS.
