Abstract

For the identification of unknown drugs in biological samples, we attempted rapid high performance thin layer chromatographic method which is sensitive and selective chromatographic analysis of high performance thin layer chromatography (HPTLC) with automated TLC sampler and ultra-violet (UV) scanner. We constructed HPTLC database (DB) on two hundred five drugs by using the data of Rf values and UV spectra (scan 200-360 nm) as well as gas chromatography/mass spectrometry (GC/MS) DB on ninety six drugs by using the data of relative retention time (RRT) on lidocain and mass spectra. After extracting drugs in biological sample by solid phase extraction (Clean Screen ZSDAU020), we applied them to HPTLC and GC/MS DB. Drugs, especially extracted from biological samples, showed good matching ratio to HPTLC DB and these drugs were confirmed by GC/MS. In conclusion, this DB system is thought to be very useful method for the screening of unknown drugs in biological samples.

생체시료에서 미지 의약품의 검출을 위하여, 민감하고 선택적인 박층크로마토그래피인 자동화 점적기 및 자외선 스펙트럼 검출기를 장착한 고성능박층크로마토그라피(HPTLC)를 시도하였다. 205종의 의약품에 대한 Rf값과 자외선흡수스펙트럼(scan 200-360 nm)을 이용하여 HPTLC 데이터베이스를 구축하였으며, 또한 96종의 의약품에 대하여는 리도카인에 대한 상대적 머무름시간(relative retention time; RRT) 및 질량스펙트럼을 이용하여 GC/MS 데이터베이스를 구축하였다. 생체시료중 의약품성분은 고상추출법(Clean Screen ZSDAU020)으로 추출한 후, 이들 시료들을 HPTLC 및 GC/MS 데이터베이스에 적용시켜 검색한 결과 90% 이상의 매우 양호한 일치율로 검색할 수 있었으며, 이들 의약품들을 GC/MS로 확인하였다. 결론적으로, 우리가 구축한 HPTLC 및 GC/MS 데이터베이스체계는 생체시료에서 미지의 의약품성분을 검색하는데 매우 유용한 방법으로 사료된다.
