We investigated whether Cirsium maritimum Makino can inhibit immunoglobulin-E-mediated allergic response in rat basophilic leukemia (RBL-2H3) cells and passive cutaneous anaphylaxis (PCA) in BALB/c mice. In vitro, the ethyl acetate extract of C. maritimum Makino (ECMM) significantly inhibitedβ-hexosaminidase release and decreased intracellular Calevels in RBL-2H3 cells. Moreover, ECMM leaves more strongly suppressed the release ofβ-hexosaminidase than ECMM flowers. ECMM leaves also significantly suppressed the PCA reaction in the murine model. High-performance liquid chromatography andH andC nuclear magnetic resonance indicated that cirsimaritin, a flavonoid, was concentrated in active fractions of the extract. Our findings suggest that ECMM leaves have a potential regulatory effect on allergic reactions that may be mediated by mast cells. Furthermore, cirsimaritin may be the active anti-allergic component in C. maritimum Makino.
