Identification and Quantification Analysis on the Chemical Constituents from Traditional Mongolian Medicine Flos Scabiosae Using UHPLC–DAD–Q-TOF-MS Combined with UHPLC–QqQ-MS

In this study, a systematic method was established for the qualitative and quantitative analysis of the major constituents in Flos Scabiosae (FS). First, Ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UHPLC–Q-TOF-MS) was developed for the identification of the multi-constituents in FS. A total of 48 compounds (9 phenolic acids, 24 flavonoids, 8 iridoids and 7 others) were unambiguously or...
