천식과 관련하여 산화스트레스 (Oxidant stress)는 그 발병요인 중의 하나로 알려져 있다. 이에 본 연구는 농산물과 한약재를 이용하여 항산화 물질을 찾고자 하였으며, 시간과 비용의 단축을 위하여 HTS인 throughput screening)을 이용을 하였다. 항산화 실험과 관련하여서 DPPH(1,1-diphenyl-2-picrylhydrazyl), FRAP(ferric ion reducing antioxidant power), HO(h
Oxidant stress is a well-known pivotal parameter for the degenerative immune diseases including asthma, atopic dermatitis, and rhinitis. In order to screen for anti-asthma agents effectively, we first established the infrastructure of high throughput screening(HTS) for anti-oxidant agents from agricultural products and/or oriental medicine library extracted with water, methanol, dimethyl sulfoxide, ethyl acetate and juice, Using the screening system, we found that Chaenomelis langenariae, Rhus javanica L., Camellia sinensis, Helianthus annuus and Angelica utilis Makino had strong anti-oxidant activity. Moreover, Helianthus annuus, Rehmannia glutinosa Libo and Angelica utilis Makino have protection activities by treatment of an oxidant hydrogen peroxide. Together, these results suggest that screened agents could be potential agents against asthma, although the in vivo studies should be clearly tested.
