Abstract

The invention discloses 3,4-methylenedioxy methcathinone detection methods. One method in the invention performs organic solvent extraction on Methylone in a suspected drug sample, performs qualitative analysis by using gas chromatography-mass spectrography (GC-MS), and performs quantitative analysis on Methylone by using a gas chromatography-flame ionization detector (GC-FID). The other method inthe method performs organic solvent extraction on Methylone in the suspected drug sample, performs qualitative analysis in a multi-reaction monitoring (MRM) mode by using a liquid chromatography-tandem mass spectrometry (LC-MS / MS), and performs quantitative analysis on Methylone by using a liquid chromatography-diode array or ultraviolet detector (LC-DVD) or LC-UV).

Description

technical field [0001] The invention belongs to the field of drug judicial detection, and in particular relates to a detection method of 3,4-methylenedioxymethcathinone. Background technique [0002] New psychoactive substances, English name New psychoactive substances, referred to as NPS, early called Legal Highs or Designer Drug, Chinese called "legal stimulants" or "planning drugs", is the research and production of some controlled drugs in order to avoid crackdowns. The drug analogs obtained by structural modification have similar effects to controlled drugs, and some have stronger excitatory, hallucinogenic, and anesthetic effects. The United Nations Office on Drugs and Crime (UNODC) divides new psychoactive substances into 9 categories, namely: synthetic cannabinoids, cathinones, phenethylamines, tryptamines, piperazines, ketamines and benzene rings. Ridines, aminoindenes, plants and others. [0003] At present, the research on new psychoactive substances in our coun...
