Objective:To determine the optimum extraction of flavone from Persimmon leaves.Method: The effects of extraction time and frequency
solid to liquid ratio
level of alcohol on the extraction rate of flavone was investigated with Rutosids
Meletin
Hyperoside as index;the optimum extraction of flavone from Persimmon leaves was determined by orthogonal experiment.Result: The optimum flavone from Persimmon leaves were: the extraction time was 1 h
the level of alcohol was 70%
solid to liquid ratio(g·mL)was 1∶ 8
and it was extracted two times.Conclusion: The optimum extraction process is achieved
