Result
2
A total of 31 chemical constituents in Microctis Folium were identified by confirmation of reference substances, literature comparison and high resolution mass spectrometry data analysis. The chemical constituent cluster was composed of 28 flavonoids (9 flavone C-glycosides, 10 flavonols and their glycosides, 8 proanthocyanidins, 1 xanthone) and 3 organic acids (caffeic acid,
p
-coumaric acid, ferulic acid).
Conclusion
2
UPLC-Q-TOF-MS/MS technique provides a simple, rapid and accurate method for the identification of chemical constituents in Microctis Folium. Flavone C-glycosides, flavonol oxyglycosides and proanthocyanidins are the main chemical constituents. The 7 proanthocyanidins are reported for the first time in this herb. In conclusion, the chemical profile of Microctis Folium is characterized and the findings are meaningful for the in-depth quality assessment and material basis clarification of Microctis Folium.
