The ammonia/desorption chemical ionization (DCI) mass spectra of nine cyclopentaoe iridoid glucosides were measured. The dependences of the intensities of different peaks on the structures and stereochemistries of the compounds investigated is discussed.
## Abstract Desorption/chemical ionization mass spectrometry (D/CI.βMS.) is a recently developed technique especially indicated for highly polar and non volatile compounds. Various naturally occurring glycosides such as saponins, iridoid and secoiridoid glycosides, cardenolides and flavoneβ__O__βgl
