Abstract
A method for identifying an origin ofis provided, which belongs to the technical field of chemical analysis and detection, and comprises the following steps: mixingextract with aluminum ion solution, and gold nano-clusters (AuNCs) solution in a solvent, standing for reaction, detecting fluorescence intensity of, comparing the fluorescence intensity ofto be detected with that offrom a target origin, and determining whether they are from a same origin. According to the application, excited-state intramolecular proton transfer effect between 3-hydroxyflavone derivatives ofand aluminum ions is utilized to enhance the fluorescence of 3-hydroxyflavone derivatives, where AuNCs combines aluminum ions to enhance aggregation-induced fluorescence, and reacts with flavonoids to quench their fluorescence; and visual characterization and traceability ofquality are achieved by further comparing obvious rich fluorescence color changes before and after the reaction.
