Abstract: The extraction technology of flavonoids from Catalpa Ovata G. Don. was studied. Main factors influencing the extraction of flavonoids from the fruit of Catalpa Ovata G. Don. were studied by single factor tests, and the optimum technology extracting flavonoids from the fruit of Catalpa Ovata G. Don. was studied by orthogonal test. Optimized conditions for the extraction of flavonoids was obtained as: ethanol concentration 60%, extraction temperature 70℃, material to solvent 1:20, extraction time 2.0 h, and extract yield is 4.83%.

Key words: Catalpa Ovata G., flavonoid, extraction
