Abstract

It is well known that the Petasites japonicum have been used for a long time in traditional medicine for the treatment of allergic diseases such as lacquer poisoning and asthma. Anti-allergic actions of Petasites japonicum extracts were asessed by testing their effects on the degranulation of mast cells. For this, hexosaminidase released (degranulation marker) from RBL-2H3 cells(mast cell line) was used. At the concentration of 300 $\mu\textrm{g}$/mL of the methanol, ethylacetate and hot water extract, the degranulation of RBL-2H3 cells were inhibited 83.33, 69.75 and 35.4%, respectively. These results suggest that the Petasites japonicum could be provide a effective resource for the control of allergic diseases.

본 연구에서는 민간에서 옻나무에 의 한 알레르기반응 및 기관지천식의 치료 효과가 있는 것으로 알려진 머위(Petasites japonicum)추출물의 항알레르기 효과를 RBL-2H3 세포로부터 hexosaminidase의 방풀 억제 정도를 측정하는 enzyme assay를 이용하여 검색하였다. 실험결과에 대한 오차범위가 낮은 추추출 300 $\mu\textrm{g}$/mL 농도의 수준에서 methanol 추출물은 83.33%, ethylacetate 추출물은 69.75%, 열수 추출물은 50.62%의 저해효과를 나타냈으며, 대조구로 사용한 quercetin은 같은 농도에서 85.80%의 저해 효과를 나타냈다. 따라서 정제된 quercetin의 hexosaminidase의 방출 억제 활성을 비교해 볼 때 머위 추출물이 조추출물 상태인 점을 고려한다면 상당한 항알레르기 효과가 있음을 시사하고 있어 새로운 항알레르기성 신기능 물질로의 이용방안을 탐색하는 기초자료가 되리라 사교된다.
