n recent years, abuse of illicit drug has been a very important problem.

Significant amount of unknown illicit substances are sized by law

enforcement and boarder protection agencies. Synthetic cannabinoids and

cathinones have a psychoactive effect on our bodies. The identification of

these drugs is important not only for the proof of the crime, but also human

health. Generally, to identify the illicit drugs, we use the techniques such

as gas chromatography-mass spectrometry (GC-MS) and high performance

liquid chromatography-mass spectrometry (HPLC-MS). These instruments,

however, are not always convenient owing to their high cost of running, the

need for trained personnel, lengthy analysis times, etc. Screening kits for detecting drugs, therefore, are required at the scene of

crime and the development of them is desired. In this study, we have designed the screening kit for cathinones to provide easily

an indication of the presence or absence of cathinones in a test sample. This kit consists of a glass tube enclosed reagents which

react with them (named “cathinone detector tube”). This kit utilizes the reaction of cathinons with neocuproine and copper(II)

to give a colored copper(I)-neocuproine complex. The presumptive color test method for the detection of synthetic cathinones

by Morgan Philip, et al. is applied to the development of this screening kit. They describe that nepcuproine color test displays

good selectivity to cathinone analogs. To improve operativity and preservation of our kit, three aqueous solutions were coated

on silica gel particle and then the powders have been enclosed in a single glass tube. The reagent in the tube colored orange

from light blue in the presence of cathinones. In consequence, this kit had very high sensitivity for detecting cathinones. The

limit of detection of α-PVP, for example, was 5 µg (absolute amount, 100 µL of 50 µg/mL solution).
