新疆不同区域沙枣中总糖、多糖与鞣质的含量比较研究

Comparison study on the contents of total sugar,polysaccharides and tannins in elaeagnus angustifolia from different area of Xinjiang

目的:对新疆不同区域沙枣中总糖、和鞣质的含量进行测定并比较。方法:本人用苯酚-硫酸法测定沙枣中总糖、多糖的含量,以磷钼钨酸-干酪素比色法测定鞣质的含量,以沙枣中总糖、多糖和鞣质的含量为考察指标。结果:苯酚-硫酸法和磷钼钨酸-干酪素的各项方法学指标符合要求,可做为测定沙枣药材质量研究的方法。沙枣中总糖、多糖和鞣质的平均含量分别为(59.7±3.14)%、(9.76±0.74)%和(0.34±0.03)%。结论:新疆不同产地沙枣中多糖,总糖,鞣质含量没有较大的差异。

Objective： To compare the content of total sugar, polysaccharides and tannins in elaeagnus angustifolia in different area of Xinjiang. Methods： The content of total sugar, polysaccharides were measured colorimetrically by the method of phenol-sulfuric acid, and the casein method to tannins, with the content of total sugar, polysaecharides and tannins as assessment indexes, respectively. Results： The methodological indexes of the detecting methods above meet the requirement of study to medicinal material. The content of total sugar, polysaceharides and tannins were （59.7±3.14）%, （9.76±0.74）% and （0.34±0.35）%, respectively. Conclusion： There were no significant difference in the contents of total sugar, polysaccharides and tannins from different places in Xinjiang .
