| Abstract: | Dihydromyricetin-Ni(Ⅱ) was prepared by the heating reflux method with dihydromyricetin as a ligand. The compex was characterized by IR spectra and UV spectra. The hydroxyl radical scavenge effect of the dihydromyricetin and the complex was compared by Fenton method. The results showed that dihydromyricetin-Ni(Ⅱ) was prepared with khaki color and the hydroxyl radical scavenge capacity of dihydromyricetin-Ni(Ⅱ) complex was stronger than that of dihydromyricetin. |
