Zusammenfassung:A new HPLC method for the analysis of cyanobacterial toxins, i.e. microcystin was developed using cyano-type prepacked cartridge while the conventional method was to utilize ODS cartridge. The cartridge was washed with 0.5 M acetic acid, then microcystins RR and LR were eluted from the cartridge with 30% acetonitrile. A better degree of quantitation was observed than with a ODS cartridge. Especially, in the case of microcystin LR a great difference in peak area was observed. 남조류의 독성물질인 microcystin을 HPLC로 분석하기 위해 지금까지는 ODS cartridge를 사용하였으나 본 연구에서는 CN cartridge를 사용하는 새로운 분석 방법을 시도하였다. CN cartridge는 0.5M 초산 용액으로 처리되었으며 Microcystins RR과 LR을 용리시키기 위해 30% Acetonitrile 용액이 사용되었다. CN cartridge를 이용하는 분석 방법이 기존의 ODS cartridge를 이용하는 방법보다 훨씬 더 정확한 정량을 할 수 있었다. 특히 Microcystin LR의 경우 피크 면적에서 현저한 차이를 보였다.
