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.
