Determination of cocaine and heroin with their respective metabolites in meconium by gas chromatography‐mass spectrometry

Abstract: The analysis of meconium specimens is a relatively accurate method for the detection of fetal exposure to drugs. The purpose of this study was to develop and validate a method for meconium sample preparation for a gas chromatography-mass spectrometry (GC-MS) confirmation of meconium extracts for cocaine, benzoylecgonine, codeine, morphine and 6-monoacetylmorphine. The analytes were initially extracted from the matrix by methanol. is a product of maternal consumption, metabolism and elimination, placental trans… Show more

“…Os procedimentos baseiam-se na homogeneização da amostra em solvente orgânico para extração inicial dos analitos (extração sólido-líquido -SLE). Posteriormente, técnicas tradicionais de extração, como a extração líquido-líquido (LLE) e a extração em fase sólida (SPE), são utilizadas para purificação do extrato obtido na homogeneização, sendo os biomarcadores identificados por cromatografia gasosa ou líquida, ambas acopladas à espectrometria de massas (ABUSADA et al, 1993;ELSOHLY et al, 1998;ELSOHLY et al, 1999;FENG et al, 2000;XIA et al, 2000;PICHINI et al, 2003;COLES et al, 2005;PICHINI et al, 2005;MARCHEI et al, 2006;LOPEZ et al, 2007;MARIN et al, 2007;GRAY et al, 2009;GRAY et al, 2010b;RISTIMAA et al, 2010;ALVES et al, 2012).…”

“…Estes procedimentos levam, em média, 30 a 50 minutos para serem concluídos. O resíduo é então ressuspendido em solvente adequado para subsequente extração em fase sólida (ABUSADA et al, 1993;ELSOHLY et al, 1999;XIA et al, 2000;PICHINI et al, 2003;PICHINI et al, 2005;LOPEZ et al, 2007;GRAY et al, 2009;ALVES et al, 2012).…”
