Abstract

The invention discloses a method for detecting residual in a plurality of tranquilizers in a meat product. The method comprises the following steps: extracting and purifying by adopting a C18 solid phase extracting column, and then detecting by adopting a gas chromatography-mass spectrometer (GC-MS), so as to rapidly and exactly detect out the variety and the content of the residual tranquilizers , including seven tranquilizers , namely, diazepam, oxazepam, estazolam, alprazolam, triazolam, phenobarbital and promethazine, in the meat product. The method is suitable for detecting multiple tranquilizers medicine residues in complex substrate meat products such as sausage; the method has the advantages of being low in detection limit, accurate, fast, easy and convenient in operation and economic in detection cost, and can be developed and applied in detection mechanisms.

Description

【Technical field】 [0001] The invention relates to a method for detecting residual drugs in meat products, especially a method for detecting residual diazepam, oxazepam, estazolam, alprazolam, triazolam and phenobarbital in meat products and promethazine 7 methods of tranquilizers. 【Background technique】 [0002] Sedatives (Sedatives) refer to a class of drugs that can relieve excitement, have an inhibitory effect on the central nervous system, reduce or eliminate animal mania, and restore tranquility. Commonly used drugs are: diazepam, nitrazepam, oxazepam of the benzodiazepine class, chlorpromazine, promethazine, perphenazine of the phenothiazine class, and metamizole, phenobarbital Wait. In addition to the sedative effect, many of these drugs are growth promoters, which are used as animal feed additives. When pigs and other animals eat the feed added with the above-mentioned sedatives, they will make them sleepy and less active, and promote their rapid growth. It can ch...
