Abstract

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 NH₃ or CH₄ as reactant gas.
