Abstract

The invention relates to an extraction kit, an extraction method and a detection method for drugs in hair. The extraction kit comprises a composite extract containing a disulfide bond reducing agent,a hydrogen bond blocker, a hair expansion agent and a solvent, wherein the composite extract is alkaline and has a pH of 8.5 to 10. The extraction kit for drugs in hair hydrolyzes the hair by using areduction method with no need of special pulverizing equipment and extraction equipment during the pretreatment and with short hydrolysis time and simple operation of the whole extraction process, andthe reduction method is more suitable for the requirements of rapid detection of laboratory forensic identification compared with the conventional methods such as acid methods, alkali methods, methanol solvent methods, buffer salt solution methods and enzymatic methods. Furthermore, the reagents used in the composite extract in the extraction kit are all water-soluble reagents, which are easy tobe extracted by the organic reagent liquid, so that the solution to be detected can be quickly separated. And the reagents used are basically pollution-free to the environment, non-toxic to the operator, easily removed without residue, and basically damage-free to instruments and equipment.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to a kit for extracting drugs from hair, an extraction method and a detection method. Background technique [0002] Qualitative detection of drugs in hair is a detection technology emerging in the discipline of forensic poison identification, mainly for qualitative detection of opioids, amphetamines, ketamine and other drugs. Because of the advantages of easy storage, stable compounds, and long monitoring time, hair drug detection has been used to identify drug abuse history. [0003] There are three main mechanisms for the drug to enter the hair: (1) the drug is transported to the hair follicle through the blood circulation, and combines with it during the formation of the hair medulla and hair cortex; (2) through the sweat glands and sebaceous glands during the formation of the hair shaft. (3) In the process of hair shaft formation, it enters the hair through outer layer p...
