| Abstract: | The optimum extraction technique and conditions were studied on the active physiological components(generally flavonoids)in the north shaanxi buckwheat hull. The best extraction method of flavonoids in general was optimized with response surface analysis Box-Behnken experiment of SAS. The yield of flavonoids in general is taken as criterion. Spectrophotometry is applied for the determination of flavonoids in general. The result is: ultrasonic extraction is better than ethanol extraction and supercritical CO2 extraction. The optimum conditions for the flavonoids in general extraction technique are: ratio of solvent to material 47, ultrasonic power 195 W, temperature 70 ℃, ethanol concentration 47% and extracting time 70 min. The yield of general flavonoids is 4.84%. |
