Procedures were developed for TLCidentification and GLCdetermination of meperidine and itsmetabolites, i.e., p-hydroxymeperidine, normeperidine, and meperidinic and normeperidinic acids. Meperidine, p-hydroxymeperidine, and normeperidine were extracted with ether from biologicalfluids at pH 10, whereas meperidinic and normeperidinic acids and conjugated metabolites remained in the aqueous phase
