摘要
Polygonatum cyrtonema Hua from five different areas was used as experimental material,total saponins and total flavonoids.Colorimetric analysis method was used to compare those contents.The results showed that the contents of Polygonatum polysaccharides from different areas were in the range of 8.09%~11.78%,whereas the content of total saponins and total flavonoids was quite different,which were 2.73%~5.01%and 0.21%~0.71%,respectively.In general,these Polygonatum samples had higher polysaccharide content with obvious differences for the contents of total saponins and a low contents of flavones.
以5个不同产地的多花黄精为试验材料,采用比色法对其多糖、总皂苷、总黄酮3种生物活性成分的含量进行了测定与分析比较。结果表明:多花黄精中的生物活性成分含量因产地不同而存在着较大差异,多糖含量在8.09%~11.78%范围内变化,以娄底地区的最高;总皂苷含量范围为2.73%~5.01%,以永州地区的最高;总黄酮含量范围为0.21%~0.71%,以张家界地区及四川省的较高。总体来看,不同产地多花黄精中多糖含量均较高,总皂苷含量居中,总黄酮含量均较低。
