摘要：
Impurity profiling analysis of methamphetamine seized in Japan has been investigated. The samples are extracted with ethyl acetate under basic conditions and the extracts are analyzed by capillary gas chromatography. The resultant profiles are compared and statistically analyzed using the Euclidian distance for evaluating similarity and/or dissimilarity among exhibits. The peak identification for comparison analysis and calculation of the distance are made automatically using commercially available software. These computerized procedures enabled us to compare profiles obtained in different laboratories and to develop a database on a national base.
