Analysis of Chemical Composition Variations in Plantaginis Semen at Different Frying Time Based on UPLC-Q-TOF/MSE
In order to explore the changes of chemical constituents in Plantaginis Semen before and after stir-frying, ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS
E
) was used to rapidly identify and semi-quantitatively analyze the differential components in Plantaginis Semen processed at different stir-frying time.

column (2.1 mm×100 mm, 1.8 μm) was employed with the mobile phase of 0.1% formic acid aqueous solution (A)-acetonitrile (B) for gradient elution (0-1 min, 5%-10%B; 1-2 min, 10%-15%B; 2-10 min, 15%-20%B; 10-12 min, 20%-40%B; 12-13 min, 40%-100%B; 13-14 min, 100%-5%B; 14-15 min, 5%B), the flow rate was 0.3 mL·min

50-1 500. MarkerLynx 4.1 software was used to find the differential compounds, and the intensity of each ion peak in samples with different stir-frying time was compared to study the content variations of these compounds.
Result
2
A total of 20 components with potential significant differences were found, among which 17 were identified and 3 were unknown, mainly including phenylethanoid glycosides, iridoid glycosides, alkaloids and others. After processing, the peak intensities of 7 compounds, such as sucrose, geniposidic acid, verbascoside and plantagoguanidinic acid A, in Plantaginis Semen decreased. The peak intensities of orobanchoside, dianthoside and plantain D increased first and then decreased during the stir-frying process. The peak intensities of 10 compounds (decaffeoylacteoside, calceolarioside A, isoacteoside, etc.) increased, and 9 of them were newly generated components.
Conclusion
2
The content and composition of the chemical components in Plantaginis Semen changed significantly after stir-frying, which may be related to the reduction of laxative effect and the enhancement of antidiarrheal and diuretic activities of Plantaginis Semen after stir-frying.
