Determination of 3,4-methylenedioxymethamphetamine (MDMA) in Confiscated Tablets by High-Performance Liquid Chromatography (HPLC) with Diode Array Detector

Abstract

Chromatographic analysis by the HPLC technique with Diode Array Detector was employed for MDMA determination. A mobile phase of methanol/water (90:10v/v) allowed a peak signal for MDMA in 16 minutes. Optimized spectrophotometric signal was obtained at a wavelength of 240 nm. The analytical curve from 5.0 to 100.0ppm of MDMA was obtained, showing a linear correlation coefficient of 0.9997 and a detection limit of 2.94ppm. This methodology was employed at the dosage of confiscated samples of ecstasy in the Scientific Police Laboratory of Ribeirão Preto-SP city.

Effects of Drugs

“…Ecstasy has easily become a widespread recreational drug due to its stimulant effects on the central nervous system [8]. Ecstasy can make you feel alarm, friendly and glib, and it can make music and shades appear to be more serious.…”

Quantification of LSD in seized samples using one chromatographic methodology for diode array detection and electrochemical detection

“…The use of HPLC in forensic researches, specifically for drug analysis involves various validated methodologies when there is a quantification purpose [10,11]. HPLC -ECD has been explored for detection of drugs and explosives substances [12], but there is a lack of works focused on the analysis of illicit drugs in seized samples.…”
