Analysis of Mdma in Ecstasy Tablets in Morocco 2157 7145 1000301 PDF
Forensic Belafkih, et al. J Forensic Res , Research Article Open Access. Avenue Cdt D. It displays effects related to amphetamine-type drugs and a set of distinctive effects like restlessness, well-being, and others effects. We collected 12 batches of samples seized by Morocco Police that were analyzed by liquid chromatography coupled to tandem Mass Spectrometry to determine MDMA concentration presents in these tablets. The method was also validated in the following parameters: linearity, limits of detection and of quantification, precision and accuracy, to permit the MDMA quantification. A great variability among ecstasy tablets compositions was detected and the toxicological features were discussed. Introduction Ecstasy is a street name originally designated for 3,4-methylenedioxymethylamphetamine MDMA Figure 1 \\\\\\\\\[1\\\\\\\\\]. It is commonly used at rave parties for its psychedelic and stimulant effects that may last between 4 and 6 h \\\\\\\\\[2\\\\\\\\\]. This drug is generally sold in the form of tablets with good appearance, with great variety of colors, shapes, and sizes and printed with various types of pictures and logos \\\\\\\\\[\\\\\\\\\]. In addition, other psychoactive compounds may be present such as cocaine, heroin, caffeine, lidocaine and others \\\\\\\\\[4\\\\\\\\\]. Indeed, tablets with similar physical method for the quantification of MDMA in ecstasy tablets. This method appearances may have different chemical compositions and the contents was validated using the most recommended guidelines for analytical of MDMA in ecstasy tablets vary from 0 to The results show that the method is Due to the usually unknown composition of these tablets, applicable by the scientific police. Twelve samples of ecstasy tablets were provided by Moroccan variability of the contents. In fact, in the s, ecstasy entered the lists Civil Police. Ultrapure water of HPLC was prepared using dispositive of internationally controlled products \\\\\\\\\[8\\\\\\\\\]. E-mail: sbelouafa yahoo. J Forensic Res 6: Furthermore, our data doi: This is an open-access article distributed under police for quantitation of MDMA in tablets and powders. Page 2 of 6. Two working 3 0. These solutions were used to prepare calibration 5. Table 1: Program time. The tubes containing the solutions were stayed in ultrasound for 15 min at 40C. Limit of detection and of quantification: LOD is the lowest The chromatograms were acquired using the analyst software amount of analyte in a sample which can be detected but not necessarily version1. It corresponds to 3 times the standard deviation of five replicates of samples. It corresponds to 10 times the standard deviation of used. Chromatographic separation of the analytes was achieved on five replicates of samples. For preparation of mobile phase, 63 g of ammonium coefficient of variation and accuracy expressed as relative difference format was dissolved in 1 L water HPLC grade. Mobile phase A: 2. Mobile phase B: 2. M ammonium format solution and 2. Eluents were sonicated before use. The The inter-day precision was evaluated by repeating the intra-day flow rate was set at 0. The used gradient program time was precision study in 3 different days. The total Validation of analytic method run time was 8 mn and the column temperature was maintained at 40C. The mass spectrometer was run in MDMA concentration range. The ion spray voltage and the source To verify the selectivity of the method are made with injections temperature were set at V and C, respectively. Nitrogen gas of low concentration standard solution until a well-resolved peak was used as the curtain gas and set at The ion source gas 1 and 2 Figure 2. No interfering peaks were observed at the retention times, were set at A summary of the ion transitions, declustering potentials, confirming the good selectivity of the method. LOD, defined as the signal-to-noise ratio , is equal areas and external standard method. Thus, the developed method is using the most recommended guidelines for analytical validation considered precise for these analytes \\\\\\\\\[25\\\\\\\\\]. Page 3 of 6. Figure 3: Representative chromatographic and mass spectra of MDMA, in tablet 2 of Table 3, analyzed using our quantitate method. Page 4 of 6. Table 3: Characteristics and quantitative results of seized ecstasy tablets. The calculated accuracy error is less than 5. So, it is considered technique and a rapid technique, demanding only basic laboratory insignificant \\\\\\\\\[24\\\\\\\\\]. These results show the high quality of quantitative equipments and glassware. The method also proved to be eective for results achievable with this method. At last, tablets, the developed method excluded the initial basic extraction step the proposed method for the quantitative analysis of MDMA in ecstasy generally described in the literature \\\\\\\\\[\\\\\\\\\]. In comparison to other tablets is suciently precise and accurate. Page 5 of 6. Clin Chem Twelve forensic samples of ecstasy tablets were used in the Figure 3 presents a chromatogram and mass d. Stereoselectivity spectra of MDMA in a tablet using our quantitate method. Table 3 and clinical evaluation. Forensic Sci Int These chemical analyses had shown great of amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine and variation in MDMA contents among the samples, from 1. J Chromatogr B Biomed Appl Ensslin HK, Kovar KA, Maurer HH Toxicological detection of the designer On the other hand, these results proved that some with similar drug 3,4-methylenedioxyethylamphetamine MDE, Eve and its metabolites in physical appearance had different MDMA contents samples 1 and urine by gas chromatography-mass spectrometry and fluorescence polarization immunoassay.

The results showed that the The linearity and accuracy were confirmed, and spectral analysis of 1- 3,4-methylenedioxyphenyl butanamines, homologues of 3,4-methylenedioxyamphetamines. The method may be used, by the scientific police, for quantitation of MDMA in pills and powders.
