Ultrasonic Extraction of Flavonoids from Persimmon Leaves Technology Research
摘要
Abstract
[Objective ] To study the technique and parameters for ultrasonic extraction of flavonoids from persimmon leaves. [ Method ] Using ultrasonic assisted method, with alkali and ethanol as solvents, ultrasonic water extraction, ultrasonic ethanol extraction technological condition was optimized. [ Results ] The optimum technique conditions by ultrasonic alkali water extraction method were: time 40 min, temperature 40 t!, solid-liquid ratio 1:30 g/ml, soaking time 6 h, the content of flavones was 5. 28% ; optimum conditions by ultrasonic ethanol extraction were; solid-liquid ratio 1:10 g/ml, ultrasonic power 200 W, extraction time 30 min. The obtained total flavone content was 6.19%. [ Conclusion] Ultrasonic water extraction method is economical and practical, which is suitable for production; ultrasonic solvent extraction method could obtain high content of flavonoids, more than 0. 8% than ultrasonic water extraction method.关键词
