Zusammenfassung:The optical purity of 11 commercial dexibuprofens and 7 ibuprofens sold in Korea in 2013 were examined by chiral HPLC. The Chiralcel OD-H column and LUX-Cellulose-1 column were used as chiral stationary phases and the mixed eluent of hexane:isopropanol:acetic acid as 100:1:0.1 was used as a mobile phase with a flow rate of 1.0 mL/min. Each data was obtained from an average value of at least three different experiments for each sample and the average value of relative standard deviation of them appeared very small, 0.19%. Average optical purity value (97.5%) of eleven commercial dexibuprofens used in this study were smaller than those of 9 years ago (99.2%), but larger than four years ago (95.6%). Enantiomeric ratios of (R)- and (S)-isomers of seven ibuprofen samples used in this experiment were achieved at about 50:50 which was different with the result (44:56) from four years ago. 2013년 국내에서 시판된 7개의 이부프로펜과 11개의 덱시부프로펜의 광학순도를 키랄 HPLC로 조사하였다. Chiralcel OD-H 칼럼과 LUX-Cellulose-1 칼럼을 키랄 정지상으로 사용하였고, hexane:isopropanol:acetic acid가 100:1:0.1로 혼합된 용액을 전개용매로 사용하여 흐름속도 1.0 mL/min에서 분석하였다. 각 시료를 최소 3회 이상 분석하여 얻은 평균값을 각각 계산하여 데이터로 이용하였고, 이들의 상대표준편차 평균값도 0.19%로 아주 작게 나타나 실험의 정밀도가 높음을 확인하였다. 실험에 사용된 11개 덱시부프로펜의 광학순도 평균값은 처음 판매가 허가된 2004년의 평균값인 99.2%에 비해 낮아졌지만 2010년의 평균값인 95.6% 보다는 높은 97.5%를 보였다. 그리고 실험에 이용된 모든 이부프로펜 두 거울상 이성질체의 조성비는 2010년 조사값(44:56)과는 달리 거의 50:50으로 얻어졌다.
