Characterization of polymeric phenolic acids and flavonoids in Clerodendranthi Spicati Herba using ultrahigh‐performance liquid chromatography coupled to quadrupole time‐of‐flight tandem mass spectrometry with target and nontarget data mining strategy

Abstract

The results indicated that the UHPLC/QTOF-MS/MS method coupled with target and nontarget data mining strategy was feasible and rational for identifying the polymeric phenolic acids and flavonoids in complex chemical constituents of CSH. The findings will be conducive to the discovery of the active ingredients of CSH and the establishment of quality standards.
