| Abstract: | The optimum extract conditions of the total flavones from Ginkgo bilobal L. were determined by experiments, the product were characterized with IR、UV、Flu. As a result , the optimum extracting and refining conditions is 1:6 of 70% ethanol to Ginkgo biolba L. weight , extraction for 2 times and 3 h for each time . 1:20 of kieselguhr to Ginkgo biolba L. weight , 2. 3:1 of 70% ethanol to Ginkgo biolba L. to wash flavones. The output rate of refined product was 3. 90% and the content of total flavones in the refined product was 93.90% |
