Abstract: A method for preparing a biflavone-iron complex, includes using the amentoflavone as the ligand and the ferric ion as the central ion, the amentoflavone-iron 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-iron complex are studied in the present invention. MTT method shows that the amentoflavone-iron complex has a relatively good 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-iron complex is stronger than that of the amentoflavone itself.

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.

Abstract: A biflavone-copper complex, a preparation method and application thereof are disclosed. The biflavone-copper complex has the following structural formula: wherein, X is NO3? or Cl?. A method of preparing the biflavone-copper complex includes the following steps: dissolving a copper salt in an alcohol and then adding into a biflavone alcoholic solution, controlling pH to 5-7; under heating and stirring, performing a reaction for 2-5 h to form a precipitate; filtering the precipitate, washing the precipitate with alcohol and water, recrystallizing the precipitate using dimethyl sulfoxide as a solvent, and drying the precipitate to obtain the biflavone-copper complex. The biflavone-copper complex is used for preparing an antitumor drug and/or an antioxidant drug.

Abstract: A method for preparing a biflavone-cobalt complex includes using the amentoflavone as the ligand and the cobalt ion as the central ion, the amentoflavone-cobalt 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-cobalt complex are studied in the present invention. MTT method shows that the amentoflavone-cobalt complex has better antitumor activity, and the antitumor activity thereof is stronger than that of the amentoflavone. Pyrogallol auto-oxidation method, ABTS method and FRAP method show that the antioxidan activity of the amentoflavone-cobalt complex is stronger than that of the amentoflavone itself. The formation of the flavonoid-cobalt complex enhances the antitumor and anti-oxidation activities of the amentoflavone, and is expected to be used in the development of drugs.
