Popis:	Mass spectrometry has been used extensively for saponin determination and structural confirmation. Sapogenins (saponin aglycones) were first studied by Budzikiewicz and coworkers using electron impact (EI) ionization.1 Hostettmann utilized desorption/chemical ionization mass spectrometry for the structure determination of triterpenoid and spirostanol saponins.2 Schulten and Soldati applied field desorption mass spectrometry for the confirmation structure of saponins from Gleditsia japonica.3 Mostad and Doehl used liquid chromatography mass spectrometry (LC-MS) with chemical ionization (CI) for the characterization of sapogenins from Gypsophila arrostii. 4 Massiot et al. used californium plasma desorption mass spectrometry (252Cf-PDMS) for structure elucidation of alfalfa root saponins.5 Numerous investigators have used fast atom bombardment (FAB) or LSIMS for saponin determination.6,7
