Abstract

The separation and determination method of racemic isomers of flurbiprofen in urine samples have been investigated using column switching- HPLC, which include the sample treatment and concentration column. The optical rotation of two isomers separated were measured to identify d-form and l-form. The calibration curves are liear in the ranges of $0.11-5.4{\mu}g/mL$ for both d-form and l-form. The detection limits were $0.031{\mu}g/mL$ for l-isomes and $0.027{\mu}g/mL$ for d-isomer. The coefficients of variation of intra-day and inter-day precision of this method were about 1.8%. The present method was apllied to determine the concentration of racemic isomers in urine sample from human eating the drug.

광학이성질체 분리 컬럼, 시료처리 및 농축 컬럼이 부착된 컬럼스위칭-HPLC를 이용하여 뇨시료에서 미량의 플루비프로펜 광학이성질체를 분리 정량하는 방법을 연구하였다. 분리된 각 이성질체의 고유광회전도를 구하고, d-이성질체 및 l-이성질체를 확인하였다. 이들의 검정선의 농도범위는 각각 $0.11{\sim}5.4{\mu}g/mL$이었으며, 검출한계는 d-이성질체의 경우 $0.027{\mu}g/mL$이고, l-이성질체의 경우 $0.031{\mu}g/mL$이며, 날자간 및 날자내의 정밀도의 CV값은 각각 1.84% 이하였다. 본 분석법은 플루비프로펜 약물을 복용한 살마의 뇨중에 존재하는 플루비프로펜의 분석에 적용하였다.
