Fluorometric Determination Of Riboflavin In Edible Plants And Foods

In this study, riboflavin spectrometric properties and electrochemical properties have been investigated using Uv-vis spectrometric and fluorometri as well as cyclic voltametric methods. Fluorometric queching of riboflavin in the presence of Na2S2O4have also been studied using sepctrometric and electrochemical determination. Selective quantitative analytical methods heve been established according to the selective fluorometric queching of riboflavin by Na2S2O4. Using this method, Rboflavin contents in some food and plants have been succesfully determined. This study give usful information for the fluorometric properties of riboflavin and for the riboflavin contents in some plants and foods.Chapter1:PrefaceThis paper proposed the purpose and significance of thesis, introduced the function of riboflavin and methods of detection. This paper introduced the main contents of the subject.Chapter2:The second chapter of riboflavin spectroscopy, electrochemical properties and the fluorescence quenching effect ofOn the different acidity and photodegradation of riboflavin absorption and fluorescence spectra of influence,. Using spectroscopic method and electrochemical method to further study with two of sodium on riboflavin quenching principle, is riboflavin isoalloxazine conjugate results has been destroyedChapter3:food and plant samples of riboflavin content determinationUse of even two of sodium on the free state of riboflavin with selective quenching effect, and the selection of traditional food, like sauce, beer and edible plants as samples for analysis, established the selective determination of matrix composition of more complex samples free riboflavin sensitive analysis method. The method and results of the study of the determination of riboflavin in the sample and provide important reference.Chapter4:the interaction of riboflavin with KarpThis paper determined through spectroscopic and electrochemical determination method, discusses the Kapp Tauli tablet and riboflavin interactions. The result shows that both had obvious interaction. This study to explore the Kapp Tauli side effects of chemical mechanism has a certain reference value.
