A fast and sensitive analytical method was developed to characterize a
rtemether and its metabolites in small amounts in body fluids. The ext
racts were derivatized with N-methyl-N-trimethylsilyltrifluoroacetamid
e, separated on an optimized capillary gas chromatographic system and
identified by chemical ionization mass spectrometry by using ammonia a
s reagent gas. The analytical assay is demonstrated on samples extract
ed from bovine hemoglobin, rat blood and dog blood. Full mass spectra
of artemether and three metabolites were obtained at a level of 1.10(-
6) g/ml. (C) 1998 Elsevier Science B.V. All rights reserved.
