Formation of inclusion complexes between riboflavin and beta-cyclodextrin (beta-CD) with both 1: 1 and 1:2 stoichiometry has been established by fluorimetric titration. However, in absorption spectrometric experiment, spectral change of riboflavin in the visible range could be observed only by taking beta-CD at a much higher concentration (about 100 times) than riboflavin and under such condition only 1:2 complexes could be detected. its formation constant (K) was determined by a multiple linear regression analysis of the absorption data. The reliability of the K value was confirmed by the consistency achieved on analyzing the data at two different wavelengths. (C) 2009 Elsevier B.V. All rights reserved.
