Abstract

Squamosten-A, a new mono-tetrahydrofuranic acetogenin possessing a double bond in the hydrocarbon chain, has been isolated from the seeds of Annona squamosa L. (Annonaceae). The structure has been elucidated on the basis of spectral evidence, including precursor-ion scanning spectra. Chemical degradation was successfully employed to determine the position of the double bond.
