Abstract: An ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) technology was used to quickly and comprehensively analyze the chemical components of American ginseng fruit pedicels, UNIFI natural product analysis platform was then applied to compare the retention time of each component, accurate molecular mass and fragment ion information. There are 101 chemical components identified or preliminary identified, mainly including 74 triterpene saponins, 5 steroids, 11 organic acids and organic acid esters. The results show that American ginseng fruit pedicels are rich in ginsenosides and should be used as natural resources of saponins. This study can provide a theoretical basis for the rational development and application of American ginseng fruit pedicels resources.
