Abstract
The present invention discloses a biflavone-zinc complex, a preparation method and application thereof. In the present invention, using the amentoflavone as the ligand and the zinc ion as the central ion, the amentoflavone-zinc complex is obtained by reaction, and the structure of the complex is characterized by infrared spectroscopy, UV-vis absorption spectroscopy and high resolution mass spectrometry. Meanwhile, the antitumor and antioxidant activities of the amentoflavone-zinc complex are studied in the present invention. MTT method shows that the amentoflavone-zinc complex has better antitumor activity, and the antitumor activity thereof is stronger than that of the amentoflavone. Pyrogallol auto-oxidation method and ABTS method show that the antioxidative activity of the amentoflavone-zinc complex is stronger than that of the amentoflavone itself. The formation of the flavonoid-zinc complex enhances the antitumor and anti-oxidation activities of the amentoflavone, and is expected to be used in the development of drugs.
