Background : Allergy is a common disease caused by type I hypersensitivity reaction of the immune system. Unfortunately, there is no proper treatment for allergy. Therefore, the discovery of therapeutic drugs for allergy is essential. In this study, the crude extracts of 56 plant parts were screened for anti-allergy effects in RBL-2H3 cells. Methods and Results : IgE-sensitized RBL-2H3 cells were individually treated with 56 extracts of medicinal herbs at the final concentration of 20 ㎍/㎖ and stimulated with the antigen DNP-BSA. β-Hexosaminidase release, interleukin-4 (IL-4) secretion, and cell viability in the sample treated cells were measured. Among the tested samples, extracts from the root of Polygonatum stenophyllum Maxim., aerial part of Acer triflorum Kom., and leaf of Pyrus pyrifolia var. culta (Makino) Nakai showed inhibitory effects on β-hexosaminidase release. The aerial part of Peucedanum japonicum Thunberg and seed of Panax ginseng C.A.Mey. showed suppressive activities on IL-4 secretion. All of the extracts were not cytotoxic at the tested concentration. Conclusion : From the result, six extracts including Polygonatum stenophyllum Maxim. (root) and Acer triflorum Kom. (aerial part) inhibited both β-hexosaminidase release and IL-4 secretion in IgE-sensitized RBL-2H3 cells. The use of these extracts for developing anti-allergy materials is suggested.
