摘　　要：以醇提法提取沙枣树不同部位的黄酮类化合物,并利用NaNO2-Al(NO)3-NaOH显色体系紫外吸光光度法测定沙枣树各部位总黄酮含量,对黄酮类化合物在沙枣树中的分布规律进行分析研究。结果表明沙枣树中总黄酮分布分别为:树皮含37.0 mg/g,木质部含14.3 mg/g,果实含1.6 mg/g,叶子含18.8 mg/g,种子含18.6 mg/g。研究结果揭示,沙枣树不同部位总黄酮的含量有显著差异,其中沙枣树皮中含量最高,果实中含量最低。Flavonoids were extracted with 95% ethanol from bark,wood,leaf,fruit and seed of Elaeagnus angustifolia L（Elaegnaceae）,and the total flavonoid content of each part was determined by UV spectrophotometry method.The distribution rule of flavonoids in Elaeagnus angustifolia was thus investigated.The results showed that total flavonoid contens of Elaeagnus angustifolia bark,wood,fruit,leaf and seed were around 37.0 mg/g,14.3 mg/g,1.6 mg/g,18.8 mg/g and 18.6 mg/g,respectively.This study indicated that flavonoid contents in different parts of Elaeagnus angustifolia varied considerably,with the maximum of bark 37 mg/g,whereas fruit,the minimum flavonoid content,only 1.6 mg/g.
