Table 3: _Cont._Pytochemistry research studies have demonstrated that the chemical constituents in the _Panax_ genus are very complex [1; 22; 23]. Ginsenosides are the major effective components. Currently, hundreds of ginsenosides have been isolated and unambiguously characterized from these _Panax_ species, especially from _P. ginseng, P. quinquediium_, and _P. notoginseng_. Furthermore, the fragmentation pathways of numerous ginsenosides have been reported by numerous research studies [24; 25], which makes it easier to detect and identify secondary metabolites from _Panax_ species using the UHPLC-Q-Exactive/HRMS technique. In the present study, ESI-MS on negative ion mode was used for compound detection and characterization due to its high sensitivity and sensitivity, as well as clear mass spectra in the negative ion mode.
