摘要
目的:对不同产地红蓼中总黄酮的的含量进行比较分析。方法:以芦丁为对照品,采用紫外-可见分光光度计在509nm处测定红蓼中总黄酮的含量。结果:以此法对红蓼中总黄酮含量进行比较分析,显示不同产地的红蓼总黄酮含量最高为3.25%,含量最低为2.11%。结论:此法测定红蓼中总黄酮的含量,精密度、稳定性和重复性良好,有助于红蓼的质量控制。
Objective ： To make a comparative analysis of the total flavonoids content in Polygonum orientale L. from different habitats. Method： The total flavonoids content in Polygonum orientale L. was determined at 509 nm by UV-visible spectrophotometry with rutin as the reference substance. Result： Compared the content of total flavonoids in Polygonum orientale L. with this＇method, it showed the highest content of total flavonoids in Polygonum orientale L. was 3.25 %, while the lowest was only 2. 11%. Conclusion： The repetition, stability and precision of the method to analyze the total flavonoids content are promising. The method can be used to control the quality of Polygonura orientale L.
