Application of fluorescent compound in detecting and/or distinguishing natural plant compounds

The invention relates to the technical field of fluorescent chemical sensors, in particular to application of a fluorescent compound in detection and/or distinguishing of natural plant compounds. Theinvention discloses application of a fluorescent compound in detection and/or distinguishing of natural plant compounds. The structural formula of the fluorescent compound is shown in the specification, wherein n is any one of 1, 2, 3, 4, 5, 6, 7 or 8. The fluorescent compound adopted by the invention is an AIE compound, and can realize the detection of natural compounds through the change of fluorescence emission intensity or fluorescence emission wavelength. According to the invention, the lightening type response to oleanolic acid can be realized by increasing the fluorescence emission intensity; the response to liquiritin can be realized through fluorescence emission wavelength blue shift; glycyrrhizic acid, glycyrrhetinic acid, oleanolic acid and liquiritin can be distinguished through one-time detection. 本发明
