Following to the synthesis of riboflavin tetrapalmitate, a fat-soluble riboflavin derivative, we intended to synthesize other fatty acid esters of riboflavin to apply them to nutritional field. Riboflavin caprate and butyrate were prepared in the similar way as riboflavin tetrapalmitate. The absorption spectra and fluorescence emission spectra of their alcoholic solution were estimated, and their Rf values for various solvents were also obtained. Then, chemical structure of the above two derivatives were studied by the estimation of riboflavin and fatty acid in their molecules, and by the test of periodate oxidation. The experimental results showed that these two derivatives are riboflavin-2', 3' 4', 5'-tetracaprate and riboflavin-2', 3', 4', 5,' tetrabutyrate.
