Abstract: Elaeagnus angustifolia is usually used in the treatment of spleen and stomach, indigestion, enteritis, diarrhea, cough and other diseases. In this study, the homogenate extraction method and the traditional method were compared by single factor experiment, and the method of homogenate extraction total flavonoids from E.angustifolia fruit was determined. The optimum technology conditions were as follows:ethanol concentration was 55%, solid-liquid ratio was 1:30 g·mL-1 and the extraction time was 5 min. Under the optimal conditions, the total flavonoids of E.angustifolia fruit yield rate was 6.57%. This study would provide a theoretical basis for the comprehensive development and utilization of E.angustifolia fruit.

Key words: Elaeagnus angustifolia, total flavonoids, homogenate extraction
