The inclusion complex of beta-cyclodextrin (beta-CD) and osthole was studied by the electrospray ionization mass spectrometry (ESI-MS) and fluorescence spectrometry. From the mass spectrum, the 1:1 stoichiometric inclusion complex of beta-CD and osthole was observed. The tandem mass spectrum was performed. The fluorescence intensity of osthole increased in the present of beta-CD. According to the 1:1 beta-CD-osthole mode, the dissociation constant (KD) was obtained by ESI-MS and fluorescence spectrometry. The KD of beta-CD-osthole inclusion complex is 6.96 x 10(-3) mol L(-1) obtained by mass spectrometry and that is 8.14 x10 (-3) mol L(-1) obtained by fluorescence spectrometry, which is consistent with each other.
