The study on the fluorescence of flavonoid compounds
This paper has been introduced the theory of fluorescence and the factors of fluorescence properties, such as molecular structure. The fluorescence probe and the recognizing mechanism were also reviewed in this paper. At the same time, the extraction methods, determination method and the biological activities of flavonoids compounds were summarized. And in this paper, taking quercetin and morin for examples, the detection method of flavonoid compounds by fluorescence spectrophotometer based on fluorescence property of flavonoid compounds were reviewed. And the detection methods of metal ions by flavonoid compounds as fluorescence probe were also introduced in this paper.
Key words：Flavonoid compounds, Fluorescence property, Fluorescence probe
