The aim of the study was to synthesize the complexes of Wogonin with β-CD and HP-β-CD by refluxing method, and the experimental resulted confirmed the forming of Wogonin complexes with CDs by nuclear magnetic resonance spectroscopy, infrared spectra and differential scanning calorimetry at 60 ℃ refluxing for 6h. Kinetic studies of DPPH with Wogonin and CDs complexes were done. The results obtained indicated that the Wogonin/HP-β-CD complex was the most reactive form.
