中文摘要	the non-covalent complexes between three flavonoid glycosides (quercitrin, hyperoside and rutin) and heptakis(2,6-di-o-methyl)-beta-cyclodextrin (dm-beta-cd) were investigated by electrospray ionization fourier transform ion cyclotron resonance mass spectrometry (esi-fticr-ms). the 1:1 complexation of each flavonoid glycoside (guest) to the dm-beta-cd (host) was monitored in the negative ion mode by mixing each guest with an up to 30-fold molar excess of the host. the binding constants for all complexes were calculated by a linear equation in the order: dm-beta-cd:quercitrin > dm-beta-cd:rutin > dm-beta-cd:hyperoside. a binding model for the complexes has also been proposed based on the binding constants and tandem mass spectrometric data of these complexes.
