Abstract

The invention relates to a graphene QuEChERS method-based UPLC-MS / MS detection method established for liposoluble phycotoxins. The UPLC-MS / MS quantitative detection method for the nine liposoluble phycotoxins in shellfish aquatic products is established. The method has the advantages of rapidness, simplicity, convenience, high efficiency, high recycle rate, less contact with organic solvent, timesaving and the like. By the established QuEChERS sample pre-treatment technology, the freezing and degreasing technology and the high adsorption property of graphene oxide, complex matrixes (such as free fatty acid and pigment) can be removed effectively, the good detection recovery effect on the liposoluble phycotoxins can be obtained, and the purification effect is good. The low-temperature refrigeration technology is introduced to assist the QuEChERS method in purifying samples, so that matrix benefits can be reduced remarkably, and the sensitivity of the methods can be improved. The UPLC-MS / MS technology is combined, detection of the liposoluble phycotoxins in shellfish samples is applied successfully, the nine liposoluble phycotoxins can be detected at the same time, more five liposoluble phycotoxins are detected than existing standard methods, and high applicability is achieved.

Description

technical field [0001] The invention relates to a detection method for fat-soluble shellfish toxins, in particular to a UPLC-MS / MS multi-component quantitative detection method for fat-soluble shellfish toxins established by the QuEChERS method based on graphene oxide, which reduces the matrix benefit and improves the sensitivity of the method . Background technique [0002] Marine biotoxins (shellfish toxins) specifically refer to a large class of small molecule toxic chemicals that are mainly produced by marine toxic microalgae or microorganisms, can be enriched in marine organisms, especially bivalve molluscs, and are harmful to other organisms including humans. substance. For these biological toxins, researchers initially divided them into six categories based on the symptoms of poisoning they caused: Paralytic Shellfish Poisoning (PSP), Diarrhetic Shellfish Poisoning (DSP), Neurotoxicity Shellfish poisoning (Neurotoxic Shellfish Poisoning, NSP), amnesic shellfish pois...
