陕西产黄精不同炮制品中多糖含量分析

Analysis of Polysaccharide Content in Different Processed Products of Polygonatum from Shaanxi

目的:本文探讨陕西产黄精不同炮制品中多糖含量变化规律。方法:采用紫外可见分光光度法,经过0.2%蒽酮-浓硫酸显色,在波长580 nm处对陕西产区黄精不同炮制方法所得饮片中多糖含量进行测定并进行分析。结果:陕西产黄精不同炮制品中多糖含量存在显著差异,以黄精生饮片中多糖含量最高,酒蒸品次之,清蒸品最低。另外,黄精不同炮制品中浸出物和多糖含量变化规律一致。结论:本研究结果为陕西产黄精饮片的质量控制和饮片炮制方法提供参考依据。

Objective： To study the change rule of polysaccharide content in different processed products of polygonatum from Shaanxi. Methods： The content of polysaccharides was determined by UV spectrophotometry at the wavelength of 580nm after colored by 0.2% anthranone-sulfuric acid solution. Results ： The content of polysaccharide was significantly different among different processed products of polygonatum, and that in the raw slices was the highest followed by alcohol evaporate slices, while that in the steamed samples was the lowest. Furthermore, the extract and the content in the different processed samples of polygonatum showed a similar regularity. Conclusion： The results of the research can provide reference for the quality control and processing methods of polygonatum slices from Shannxi.
