Abstract

The invention discloses a pretreatment method for detecting cannabinoid new psychiatric active substances in grease. By combining the method with technologies such as high performance liquid chromatography, gas chromatography, high performance liquid chromatography-mass spectrometry and the like, cannabinoid can be better extracted and separated from a grease sample, the detection of cannabinoid in grease is realized, and the operation is simple, quick, accurate and reliable.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and proposes a high-efficiency pretreatment method for detecting multiple cannabinoid new psychoactive substances in oils and fats. Background technique [0002] Industrial hemp is an extremely valuable economic crop. Foreign countries have gradually liberalized the control of hemp including industrial hemp. my country has also included hemp seed (a fruit of industrial hemp) in the list of medicinal and edible homologous products. It is also available on the market. Foods such as hemp oil, hemp seed and hemp paste appeared. However, studies have shown that when humans ingest more than 0.3% cannabinoids, they show psychoactive properties. For this reason, the United Nations Convention and the laws of many countries have listed them as "narcotics" or "drugs" and adopted control measures. Due to the strong fat solubility of cannabinoids, it is difficult to separate them from oils and fats in the ...
