Objective: To establish the optimum preparation of total flavonoids from Flos Carthami and Radix Astragali. Method: By water extraction and alcohol precipitation method
the optimal conditions
such as extraction temperature
extraction time
solvent quantity and extraction times were determined by orthogonal design. The total flavonoid was further prepared by AB-8 macroporous resin chromatography. Result: The optimum extraction procedure was determined with 16 times of water
60 ℃
2 hours and 3 times. of extraction. The total flavonoids could reach to 78.6% and hydroxy safflor yellow A(HYSA) reach to 10.07% after further purification with AB-8 macroporous resin chromatography. Conclusion: This technique is suitable to prepare total flavonoids of Flos Carthami and Radix Astragali.
