The recoveries of most compounds ranged from 60.7% to 127%. The limits of detection were 1.4 (Scoparone (1))~70 (Naringenin (4)) ng/mL, and the limits of quantification were 4.7 (Scoparone (1))~241 (Naringenin (4)) ng/mL. A series of validation studies were carried out under the optimal conditions, and the linear relationship and reproducibility were good. Collisional Cross Section (CCS) values for single and multiple fields were measured. The target analytes were gradient eluted in 8 min by supercritical CO 2 on a Zorbax RX-SIL column. The parameters of stationary phase, mobile phase, make-up solution, temperature, and back pressure were optimized. In this study, matrix solid phase dispersion (MSPD) microextraction combined with supercritical fluid chromatography-ion mobility quadrupole time-of-flight mass spectrometry (SFC/IM-QTOF-MS) was used to analyze the multipolar compounds in plant tea.
