葛根、槐花饮片及其免煎颗粒中黄酮类有效成分的含量比较

目的:探讨比较葛根、槐花及其免煎颗粒中黄酮类有效成分的含量,为进一步确认中药免煎颗粒的疗效提供理论基础。方法:采用高效液相色谱(HPLC)法测定葛根、槐花及其免煎颗粒中黄酮类有效成分的含量。结果:葛根饮片、葛根免煎颗粒中葛根素含量分别为为0.01796g/g、0.01760g/g;槐花饮片、槐花免煎颗粒中芦丁含量分别为0.03725g/g、0.03131g/g。结论:免煎颗粒中有效成分的含量与传统饮片无显著差异,但其与饮片的疗效差别还有待进一步研究。

Content Comparison of Flavonoids Constituents in Pueraria Radix,Flos Sophorae Slices and their Decoct-free Granule

Objective:To compare the content of Flavonoids constituents in Pueraria Radix,Flos Sophorae slices and their decoct-free gTanule in order to provide the theoretical basis for further confirming the curative effect of boil-free granule of TCM.Methods:HPLC method was adopted to test the content of Flavonoids constituents in Pueraria Radix,Flos Sophorae slices and their decoct-free granule.Result:The content of puerarin in slices of prepared Pueraria Radix,and decoct-free Puerariae Radix granules is 0.01796g/g and 0.01760g/g respectively.The content of rutin in Flos Sophorae slices and decoct-free Flos Sophorae granules is 0.03725g/g and 0.03131 g/g respectively.Conclusions:The content of active ingredient showed no significant difference in the decoct-free granules and slices of prepared herbs.However whether there are curative differences still needs further study.
