본 실험은 알팔파의 Allelopathy와 Autotoxicity에 관련되는 생리활성 물질의 분리, 정제, 동정하기 위하여 실시되었다. 알팔파 생잎 1kg을 80% MeOH로 추출하여 silica gel TLC와 DCCC의 분리와 정제과정을 거쳐 HPLC로 동정하였다. HLPC 분석결과 4개의 phenolic 물질(salicylic acid, rutin, quercetin, scopoletin) 등이 동정되었다. 이들 물질을 이용한 발아실험에서도 모두 알팔파의 발아와 생육에 억제적으로 작용하였으며, 이 중 quercetin의 처리가 가장 억제적이었다. 따라서 최소한 이들 물질이 알팔파의 Allelopathy와 Autotoxicity에 관련하는 것으로 생각되었다.
To isolate, purity and identify of bioactive compounds involved in alfalfa allelopathy and/or autotoxicity, experiment was conducted. Isolation and separation procedures used from an 80% methanol extract of fresh alfalfa leaves(1kg), silica gel thin layer chromatography(TLC), followed by Droplet Counter Current Chromatography(DCCC). Preliminary identification was examined by high preformance lipid chromatography(HPLC). Four phenolic compound, salicylic acid, scopoletin, rutin, and quercetin, were identified and identified all compounds were phytotoxic to alfalfa seed germination and seedling growth. Among these compounds, quercetin treatment(<TEX>$10^{-3}M$</TEX>) was most inhibitory to alfalfa seed germination and seedling growth. These compounds may be, at least in part, involved autotoxicity and allelopathy.
