BACKGROUND: Three commercial biopesticides containing derris extract, which is permitted as a commercial biopesticide substances by the Environmentally-friendly Agriculture Promotion Act, have been marketed in Korea. But, the quantitative analytical method of active substances for crop protection in biopesticides containing derris extract has not known. METHODS AND RESULTS: Solid phase extraction (SPE) cartridge clean-up method for the quantitative analysis of rotenone and deguelin in biopesticides containing derris extract was developed and validated by ultra-performance liquid chromatography (UPLC). The clean-up method was established using hydrophilic lipophilic balance (HLB) SPE cartridges for the bioactive substances in biopesticides containing derris extract, and the eluate was analyzed to quantify the rotenone and deguelin by the UPLC. LOQ and recovery rates of rotenone and deguelin were 0.085 and 0.044 mg/L, 95.7 and 93.3%, respectively. The content of rotenone and deguelin in three biopesticides containing derris extract were analyzed by the developed method, the results showed 0.001-0.236 and

식물추출물로서 유기농자재의 허용 물질인 데리스란?
식물추출물로서 유기농자재의 허용물질인 데리스(Derris)는 동남아시아와 남서태평양 도서국에 자생하는 콩과의 덩굴성 식물로 isoflavonoid계 물질을 함유하고 있고, 이들은 α-glucosidase 저해, 살충, 세포독성 및 항산화 등 광범위한 생물활성을 나타내는 것으로 알려져 있다(Svasti et al., 2005; Rao et al.
식물추출물이 사용된 유기농자재는 어떻게 사용되고 있는가?
이들 중 식물추출물이 사용된 유기농자재는 193종(14.3%)으로 병해관리용, 병해충관리용, 충해관리용, 작물생육용, 토양개량 및 작물생육용 자재로 사용되고 있다.
데리스 추출물 함유 유기농자재 중두 지표성분 분석을 위한 정제방법으로 HLB cartridge를 채택한 이유는 이 분석 방법이 지표성분 분석에 사용했을 때 어떤 결과를 나타냈기 때문인가?
, 2013). 이 분석방법을 데리스 추출물 함유 유기농자재 중 지표성분 분석에 적용하였을 경우, 지표성분인 rotenone과 deguelin 회수율이 각각 92.8-100.2와 88.2-99.8%로 양호한 결과를 나타냈다. 따라서 데리스 추출물 함유 유기농자재 중두 지표성분 분석을 위한 정제방법으로 HLB cartridge를 채택하였다(Fig.
