目的研究并建立金莲花药材的质量标准。方法采用性状描述、显微鉴别、有效成分定性和定量分析等方法控制金莲花药材的质量。结果金莲花药材粉末的显微鉴别特征性强,薄层色谱的斑点清晰,定量分析采用HPLC方法同时测定了荭草素和荭草素-2“-O-β-L-半乳糖苷,平均加样回收率分别为98.42%(RSD=0.82%)、100.87%(RSD=0.86%),10批药材中二者的平均含量分别为1.31%、0.48%,并制定了二者总含量的限度。结论所用方法简便、可靠、稳定、准确,能全面控制金莲花药材的质量。
Objective To study and establish the quality standard of Trollius officinalis. Methods The quality of Trollius officinalis was controlled by trait description, microscopic identification, qualitative and quantitative analysis of active ingredients. Results The microscopic identification of the medicinal powder of Trollius officinalis was characterized strongly and the spots of the TLC were clear. Quantitative analysis of the constituents of turmeric and glycyrrhizin - 2 - ”- O - β - L - galactoside by HPLC method was carried out. The average recoveries were 98.42% (RSD = 0.82%) and 100.87% (RSD = 0.86%), respectively. The average contents of the two samples were 1.31% and 0.48% respectively, and the total contents of Conclusion The method used is simple, reliable, stable and accurate, and can fully control the quality of Trollius officinalis.
