Yejuhua (YJH) injection is a traditional Chinese medicine (TCM) injection and has a widely application in clinical practice. However, adverse drug reactions (ADRs) caused by YJH injection, majorly manifested as allergic reactions, have been reported. Hence, Effective and practical method for allergen screening and identification is needed. In this work, a LAD2/CMC model coupled online with HPLC-IT-TOF-MS system was developed to screen, analyze, and identify the allergenic components of YJH injection. A fraction was retained on the LAD2/CMC column, and identified as linarin (LN). Histamine release assay was performed by the multiple reaction monitoring (MRM) method of UPLC-ESI-MS/MS. Results showed that YJH injection and LN were in accord with their allergic effects by increasing histamine release. In conclusion, the LAD2/CMC-HPLC-IT-TOF-MS system developed in this study could be used to screen allergenic components in complex systems.
