Abstract: As one of the most commonly used medicinal plants, ginseng has been an attractive model herb for study. A wide range of analytical methods has been used to characterize its constituents. However, less effort has been devoted to the rare ginseng saponins, especially their isomers and sugar linkages. In this study, we used segmental monitoring and diagnostic ion filtering to characterize ginseng saponins by rapid liquid chromatography with time-of-flight mass spectrometry (LC-TOF-MS). By using selected diagnosti…
