摘　　要：沙枣总糖在浓盐酸的作用下发生反应,在284nm处直接测定沙枣中总糖的吸光度。在0.9～3.3mg/mL的范围内总糖的浓度与吸光度呈现良好的线性关系(r=0.999 8,n=5),平均回收率为99.78%(RSD=0.94%,n=6)。本法简单,明确,可用于沙枣中总糖的含量测定。Total sugar of Elaeagnus angusti folia L.can react by concentrated hydrochloric acid.Total sugar of Elaeagnus angusti folia L.was detected at 284 nm with UV Spectrophotometry.The calibration curve for total sugar was linear within the range of 0.9-3.3mg/mL（r=0.999 8,n=5）.The average recovery rate was 99.78%（RSD=0.94%,n=6）.The method was simple and accurate for the determination of total sugar in Elaeagnus angusti folia L.
