Desorption/Chemical ionization mass spectrometry of bitter glycosides from gentiana1.
A series of bitter secoiridoid glucosides isolated from various GENTIANA species (Gentianaceae) have been investigated by D/CI-MS. Amarogentin, amaropanin, amaroswerin, deglucosyltrifloroside, desacetylcentapicrin, gentiopicrin, swertiamarin and sweroside have been characterized by quasimolecular ions and typical fragments, using NH (3) or CH (4) as reactant gas.
