Mass spectra of a series of menthyl glycosides containing up to three sugar units produced by chemical ionization with isobutane and ammonia as reagent gases as well as ( 2 H 3 ) ammonia are reported. The applicability of this mass spectrometric method in structural characterization of the underivatized glycosides is discussed. All of the mass spectra are simple to interpret and afford useful diagnostic information about molecular weight and structural units in the molecules but little information for differentiation between the stereoisomers. The fragmentations producing the diagnostic ions have been confirmed with high resolution measurements and shift technique with ( 2 H 3 )ammonia reagent gas.
