摘要
以正丙醇-硫酸铵双水相作为提取溶剂,在超声波的辅助下从柿叶中提取黄酮;由正交试验确定提取的最优条件,结果表明以1.00 g柿叶粉末为原料,在每毫升水0.30 g硫酸铵、正丙醇与水的体积比为0.6、料液比1:45的条件下,超声波提取25 min,黄酮得率可达3.68%。
Adopts n-propanol-ammonium sulfate aqueous two-phase system coupling with ultrasonic to extract flavonoids from Persimmon leaves, By the orthogonal test to determine the optimal conditions of extraction. The results showed that： under the conditions of the dosage of ammonium sulfate 0.30 g/mL, With 1.00 g persimmon leaves powder as material, n-propanol and water ratio of 0.6, materials and liquid ratiol：45, the ultrasonic extraction of 25 min, the extraction yield of flavonoids was 3.68%.
