Abstract
녹병은 다양한 작물의 품질과 수확량에 큰 영향을 끼친다. 따라서 이들을 방제하기 위하여 효과적이고 환경친화적인 살균제의 개발이 절실하다. 본 연구에서는 한약재로부터 항균 물질을 탐색하는 과정에서, 당귀 메탄올 추출물이 Puccinia recondita에 의해 발생하는 밀 붉은녹병에 대하여 우수한 방제효과를 나타내는 것을 확인하였다. 밀 붉은녹병에 대하여 활성을 보이는 한 개의 항균물질을 silica gel chromatography, alumina column chromatography와 $C_{18}$ preparative HPLC를 통해 분리, 정제하였다. 분리한 항균물질은 EI-MS와 $^1H$-NMR의 기기 분석 결과 decursinol angelate로 동정되었다. 이 물질은 시험한 6개의 식물병 중에서 밀 붉은녹병과 고추 탄저병에 대하여 우수한 항균활성을 보였다. 또한, 당귀의 에틸아세테이트 추출물의 수화제도 밀 붉은녹병에 대해 우수한 항균활성이 보였다. 따라서 decursinol angelate와 이를 포함한 당귀 추출물을 이용할 경우 밀 붉은녹병을 방제할 수 있는 새로운 살균제의 개발이 가능하리라 생각된다. 본 논문에서 decursinol angelate에 의한 밀 붉은녹병 방제 효과를 처음 보고하는 바이다. Rust causes significant losses in the yield and quality of various crops. The development of new effective and environmentally benign agents against the pathogen is of great interest. In the course of searching a natural antifungal compound from medicinal plants, we found that the methanol extract of Angelica gigas roots had a potent control efficacy against wheat leaf rust (WLR) caused by Puccinia recondita. The antifungal substance was isolated from the methanol extract by silica gel column chromatography, alumina column chromatography and $C_{18}$ preparative HPLC. It was identified as decursinol angelate by EI-MS and $^1H$-NMR data. In in vivo test, decursinol angelate effectively suppressed the development of WLR and red pepper anthracnose (RPA) among the 6 plant diseases tested. In addition, the wettable powder-type formulation of ethyl acetate extract of A. gigas roots significantly suppressed the development of WLR. The crude extract containing decursinol angelate and the chemical appear to be a potential candidate for control of WLR. In addition, this is the first report on the in vivo antifungal activity of decursinol angelate against WLR as well as RPA.
