摘　　要：目的:为充分利用沙枣植物资源,避免资源的浪费,探讨沙枣花中总黄酮的提取及鉴别方法。方法:采用超声波乙醇浸提法从沙枣花中提取黄酮类物质,对所提取的黄酮类物质进行鉴定,并用分光光度法测定含量。结果:测得样品中总黄酮的含量1.02mg/L,回收率为102.8%,其纯度和产率均较高。结论:该方法采用全物理过程,无任何污染,是提取沙枣花中黄酮类物质的有效途径。Objective：To make use of the resources of the Flowers of Ningxia Elaeagnus angustifolia L., avoid wasting and approach the ex-traction of total flavanone and identifcation of the leaves Ningxia Elaeagnus angustifolia L.nethods：The flavonoidswere extracted by ethanol as the solvent from the Flowers of Ningxia Elaeagnus angustifolia L. with ultrasonicwave.Spectrophotome try was used to determine and extract the content of the flavanone from the Flowers of Ningxia Elaeagnus angustifolia L..Results：By this method the content of the total flavanone of the Flowers of Ningxia Elaeagnus angustifolia L. was 1.02 mg/mL and the rate of recovery was 102.8%. Conclusion ：This text provides the extraction and purification methods to get the outcome. The purity of the flavanone is very high.This method is a purely physical process and has no pollution.It is an ideal way to extract the flavanone of Flowers of Ningxia Elaeagnus angustifolia L..
