| Abstract: | The inclusion interaction of qucertin with beta-cyclodextrin and its derivatives was studied by fluorimetry. The formation constants of their inclusion complexes were determined, and the stoichiometry ratio on the formation of the inclusion complexes was determined by equimolar continueous variation method. The effect of aliphatic alcohols with short chains on inclusion process was discussed. The results showed that the inclusion ability of beta-CD and its derivatives was in the order: HP-beta-CD>M-beta-CD>beta-CD. The effect of aliphatic alcohol on complexes was related to the carbon number and volume of alcohol molecules. |
