Description

technical field

[0001] The invention relates to the field of drug detection in the criminal investigation field, in particular to a method for measuring cathinone, methcathinone, 4-methylmethcathinone and common adulterants in biological samples by using high performance liquid chromatography. Background technique

[0002] Cathinone drugs are new drugs that have appeared in recent years and are quite harmful to the human body and society. This hazard not only affects the physiological state of the human body, but also affects people's psychological activities, and an overdose may even lead to death. Cathinone drugs mainly include cathinone, methcathinone and 4-methyl methcathinone, and their chemical structural formulas are shown in formula (1) to formula (3):

[0003]

[0004] In the prior art, the liquid mass spectrometry method has been applied to the detection of cathinone, methcathinone, and 4-methylmethcathinone samples, but not for actual biological samples, becau...
