Abstract

To understand the antiallergic effect of Artemisia princeps (AP), which has been found to show inhibitory activity against degranulation and a passive cutaneous anaphylaxis (PCA) reaction, eupatilin and jaceosidin, as the active components, were isolated by degranulation-inhibitory activity-guided fractionation, with their antiallergic activity investigated. These isolated components potently inhibited the release of beta-hexosaminidase from RBL-2H3 cells induced by the IgE-antigen complex, with IC(50) values of 3.4 and 4.5muM, respectively. Eupatilin and jaceosidin potently inhibited the PCA reaction and scratching behaviors induced by IgE- antigen complex and compound 48/80, respectively. Orally administered jaceosidin more potently inhibited the PCA reaction than that of eupatilin, although the PCA reaction-inhibitory activity of intraperitoneally administered jaceosidin was nearly the same as that of eupatilin. Eupatilin and jaceosidin inhibited the gene expressions of TNF-alpha and IL-4 in RBL-2H3 cells stimulated by IgE-antigen complex. Eupatilin and jaceosidin inhibited the activation of NF-kB. Based on these findings, eupatilin and jaceosidin may be useful for protection from the PCA and itching reactions, which are IgE-mediated representative skin allergic diseases.
