摘要

[Objectives] To optimize the extraction of total flavone in folium Ginkgo biloba leaves.[Methods] Using the ultrasonic extraction method, the three levels of maximum impact were selected by each factor selection, and the optimal extraction technology was obtained by box-benhnken test design analysis.[Results] After analyzing the results, the optimal process was as follows: a time of 28.89 min and liquid/material ratio of 31.38∶ 1, the temperature was 40.74℃. In this way, NaNO 2-Al (NO 3) 3-NaOH was used as color developing agent, and the theoretical extraction of flavone in ginkgo leaf can reach 11.74 mg/g.[Conclusions] This method can be used to extract total flavonoids from G. biloba leaves with simple operation, low cost and good repeatability.
