✦ Synopsis

The seed oil of Choriosa speciosa, which is known to be rich in cyclopropene triacylglycerols, has been investigated by high-temperature gas chromatography using glass capillary columns coated with the stationary phase SOP-50 Ž . 50% diphenyl᎐50% dimethylpolysiloxane, methoxy terminated . Cyclopropene rings were characterized after a mild catalyzed hydrogenation procedure. The partial -character of the resulting cyclopropane ring supports the separation of individual triacylglycerol species on the polarizable stationary phase. Characterization of the separated compounds was performed by negative chemical ionization᎐mass spectrometry with ammonia as reagent gas.

A novel chemical ionization/fast atom bombardment (CI/FAB) source was used to analyse alkenes by chemical ionization mass spectrometry (CI-MS) using copper ions as the ionizing agent. The Cu Y -CI mass spectra showed abundant pseudomolecular adduct ions [alkene-Cu] Y and characteristic fragment ions
