当归超微细粉、浓缩颗粒与饮片水提取液主成分含量的对比研究

Study on Quality of Ultra Micro-powder, Concentrate-granules and Single Decoction Solution of Radix Angelecae Sinensis

目的 探讨当归超微细粉的内在质量。方法 采用高效液相色谱法、薄层色谱法等进行定量、定性分析。结果 当归超微细粉水提取液中主成分含量高于浓缩颗粒,而与饮片水提取液相当。结论 超微细粉使用方便、溶出率高。

Objective To explore the inner quality of ultra micro-powder. Methods The methods of HPLC, UV, TLC etc. were used for the qualitative and quantitative analysis. Results The contents of main components in single decoction solution of ultra micro-powder were higher than those in concentrate-granules, and the same as those in slice form. Conclusion The decocting rate of herbs in granule form is high.
