The invention relates to a drug extraction kit, extraction method and detection method in hair. The extraction kit comprises a composite extraction solution containing a disulfide bond reducing agent, a hydrogen bond blocker, a hair swelling agent and Solvent, the composite extract is alkaline, and the pH is 8.5-10. The drug extraction kit in hair uses the reduction method to hydrolyze the hair, no special crushing equipment and extraction equipment are required for pretreatment, the hydrolysis time is short, and the entire extraction process is simple to operate. Compared with the traditional acid method, alkali method, methanol solvent method and buffered salt solution Methods such as the enzymatic method and the enzymatic method are more suitable for the rapid detection of laboratory forensic identification. Further, the reagents used in the composite extract in the extraction kit are all water-soluble reagents, which are easy to extract liquid-liquid with organic reagents, so that the solution to be tested can be quickly separated, and the reagents used are basically non-polluting to the environment and non-toxic to operators. Easy to remove without residue, basically no damage to equipment. |
