식품 중 비만치료제 시부트라민의 유사물질인 데스메틸시부트라민을 규명하였다. 데스메틸시부트라민 함유 시료로부터 메탄올을 이용하여 대상성분을 추출하고 핵산으로 세척 등을 통하여 정제한 후 HPLC/PDA, HPLC/MS, HPLC/MSIMS 및 NMR로 확인 및 분석하였다. 또한, 식품 중 시부트라민 및 데스메틸시부라민을 분석하기 위하여 균질화한 시료를 디클로로메탄으로 추출하여 여과, 농축하고 메탄올로 희석하여 HPLC/UV로 분석하였다. 평균 회수 87~91%이었으며, 정량한계는 $2.5;{mu}g/kg$이었다. 분석 결과 식품시료 54건에서 시부트라민 및 데스메틸시부트라민이 검출되지는 않았다.
It has been elucidated desmethylsibutramine in food, that is an analogue of sibutramine used for anti-obesity drug. After separating and purifying in food samples, it was analyzed and identified by the instrument such as HPLC/PDA, HPLC/MS, HPLC/MS/MS and NMR. To analyze sibutamine and desmathylsibutramine in foods, they were analyzed and identified by HPLC/PDA after extracting in dichloromethane, filtering, concentration and diluting in methanol. The overall recoveries were ranged from 87% to 91% and the limit of quantitation was $2.5;{mu}g/kg$. As results, sibutramine and desmethylsibutramine was not detected in all the selected 54 food samples.
