Abstract

The invention provides a method for quickly detecting biogenic amine, which comprises the following steps: performing derivatization on a biogenic amine standard sample and a to-be-tested sample by derivating agent and then providing a chromophoric group, applying the sample on a chromatography material polyamide thin film, unfolding by using a developer, stopping chromatography when the front edge of the developer is 0.5 to 1 cm far away from the top of a thin film, developing, and observing the developing results. According to the invention, the polyamide thin film is used as chromatography detecting material for biogenic amine, the material is easy to obtain, the unfolding is quick, an unfolded thin layer plate can be preserved for a long time for recheck, and the quantitative estimation can be performed by using a thin layer scanner; through utilizing the developer with appropriate proportion, a target object and other components can be separated completely. Therefore, the method provided by the invention can be used for quick determination and semiquantitative detection of biogenic amine, and by using the method, the results can be obtained in the whole-process of 1 hour, and the instrument analysis requires longer time.

Description

technical field [0001] The invention belongs to the field of chromatographic analysis, in particular to a method for rapidly detecting biogenic amines. Background technique [0002] Biogenic amines are a class of nitrogen-containing aliphatic or heterocyclic low-molecular compounds, which are found in foods and beverages containing protein or free amino acids. It widely exists in the tissues of various animals and plants, and has important physiological activities. Low-concentration biogenic amines have obvious relaxation or contraction effects on blood vessels and muscles, can inhibit epileptic seizures, have important regulatory effects on mental activity and cerebral cortex, and have different degrees of positive muscle strength and positive frequency effects on the heart. However, when the human body absorbs excessive biogenic amines, it may cause allergic reactions such as headaches, respiratory disturbances, heart palpitations, and changes in blood pressure.
