Adverse drug reactions of traditional Chinese medicine injection mainly manifested as pseudo-allergic reactions. In the present study, ginsenoside Rd, Ro, and Rg3 were identified as pseudo-allergic components in Shengmai injection by a high-expression Mas-related G protein-coupled receptor X2 cell membrane chromatography coupled online with high-performance liquid chromatography and mass spectrometry. Their pseudo-allergic activities were evaluated by in vitro and in vivo assay. The three compounds were further found to induce pseudo-allergic reaction through Mas-related G protein-coupled receptor X2. Therefore, we concluded that ginsenoside Rd, Ro and Rg3 may be potential allergens that cause pseudo-allergic reactions. This study might be helpful for the safe use of Shengmai injection. © 2021 Wiley-VCH GmbH.
