3-Indolyl acetate can be solubilized in dilute ayueous solution of beta cyclodextrin. due to the formation of host-guest complex through hydrophobic interaction between the indolyl group and the inside cave of the cyclodextrin molecule.The thermodynamic parameters of the complexing process can be estimated utilizing the spectrophotometric data.
