Chuanxinlian injection is a traditional Chinese medicine injection widely used in China to treat sore throat, cough and dysentery, although a high occurrence of severe adverse reactions has been reported in clinical practice in recent years. In the present study, a human mast cell line-1 cell membrane chromatography coupled with HPLC-ESI-MS/MS method was established to screen and identify potentical anaphylactic components in chuanxinlian injection, and the dehydroandrographolide was identified as a potential anaphylactic component. In vitro anaphylactic assay showed that intracellular Ca²⁺ concentration clearly increased under dehydroandrographolide (100 μm) treatment. β-Hexosaminidase and histamine release in human mast cell line-1 cells were both markedly enhanced with increased concentrations of dehydroandrographolide, confirming the anaphylactic activity of dehydroandrographolide. The application for chuanxinlian injection in this study suggested that the developed human mast cell line-1 cell membrane chromatography coupled with HPLC-ESI-MS/MS system may be effective and rapid for screening the potentical anaphylactic components from complex samples.
