摘要：
The interactions between rutin or the inclusion complex of rutin-beta-cyclodextrin and DNA were investigated by means of cyclic voltammetry, UV-vis absorption spectroscopy and fluorescence emission spectroscopy. The apparent binding constant of rutin with DNA is found to be 2.9 x 10(4) L/mol. The results showed that the benzopyranic-4-one plane of rutin mainly intercalated into DNA in the absence of beta-cyclodextrin, while the catecholic portion of rutin was located in the double helix of DNA in the presence of beta-cyclodextrin.
