Development and validation of a reliable method for studying the distribution pattern for opiates metabolites in brain.
Journal of Pharmaceutical and Biomedical Analysis(2013)
摘要
Brain distribution pattern of “street” heroin metabolites (morphine and codeine) was investigated in two fatalities due to “acute narcotism”. A suitable sample pretreatment prior to solid-phase-extraction was developed to achieve a good recovery of the analytes and to eliminate the interfering species. After derivatization with MSTFA, samples were analyzed by GC/MS. Specificity, accuracy, precision and linearity of the method were evaluated; LOD and LOQ were, respectively, 10ng/25ng for morphine and 5ng/10ng for codeine.
