Flavonoids are the most important meat from Chengdu active ingredient, with a wide range of physiological functions, can be used for the development of functional foods. To improve Cistanche resource utilization, the development of high value-added products, and promote industrial development, this paper ultrasonic assisted extraction, microwave-assisted extraction and ethanol extraction method three extracts the active ingredient Cistanche total flavonoids were extracted. The main findings are as follows:1. Microwave-assisted extraction optimum extraction conditions for solid-liquid ratio 1:30, microwave power 800 W, 70% ethanol concentration, extraction time 3min, namely A2B3C3D2. Under the optimal extraction conditions, the measured content of flavonoids flower tube cistanche for 7.40 mg / ml.2. Ultrasonic assisted extraction optimum extraction conditions were 70% ethanol concentration, solid-liquid ratio 1:30, extraction time 40 min, extraction times 2 times. Under the optimal extraction conditions, by measuring the content of Cistanche seen in flavonoids was 8.45 mg / ml. You can get the best extraction conditions A2B2C3D2.3. Ethanol extraction optimum extraction conditions were 70% ethanol concentration, solid-liquid ratio 1:30, extraction times 1 times, the time is 2h. Ethanol extraction for extracting the best combination of Total Flavonoids of A2B3C1D1, total flavonoids Cistanche under this condition is as 7.68 mg / ml.Ultrasonic assisted extraction method extraction process tube flower Total Flavonoids than mic Ultrasonic assisted extraction method extraction process tube flower Total Flavonoids than microwave-assisted extraction and ethanol extraction. Determination of total flavonoids by absorbance values, can be obtained Cistanche Total Flavonoids in the optimum extraction conditions provide a theoretical basis for in-depth study medicine. |
