An allergy is a hypersensitivity disorder of the immune system. Arctium lappa L., known as a Burdock, is a popular edible vegetable but its anti-allergic potential remains unknown. In this study, the anti-allergic effect of A. lappa extracts was determined using Sprague-Dawley rats, ICR mice, and RBL-2H3 mast-like cells. Among fractions extracted with several solvents, EtOH fraction of A. lappa (ALE) at 100 �¼g/ml showed the maximal inhibitory effect on �²-hexosaminidase release and the high cell viability in RBL-2H3 cells. Administration of ALE (100 mg/kg) highly suppressed the passive cutaneous anaphylaxis (PCA) induced by anti-DNP-specific IgE insult in rats, and attenuated the compound 48/80-induced systemic allergic reaction, anaphylaxis, and histamine release in mice. In order to identify the active compound from ALE with antiallergic action, we subsequently performed further fractionation with determining �²-hexosaminidase assay in every subfractions and its main active component was identified as an oleamide. Oleamide attenuated the secretion of histamine and �²-hexosaminidase, and the production of allergic-related cytokines such as IL-4 and TNF-�± in RBL-2H3 cells treated with compound 48/80 or A23187/PMA. In addition, oleamide administration suppressed Fc�µRI-tyrosine kinase Lyn-mediated pathway. The anti-allergic effect of ALE and its bioactive component oleamide may have beneficial effects in the treatment of human allergic diseases.
