不同产地、不同种类以及不同部位中的石韦总黄酮含量分析

Determination of Total Flavone in Pyrrosia from Different Areas,Species and Extractive Fractions

目的:采用紫外可见分光光度法对不同产地、不同种类以及不同部位的石韦药材中的总黄酮的含量进行分析研究,对药用石韦的质量控制提供一定的依据。方法:利用60%乙醇超声提取不同石韦粉末,采用紫外-可见光分光光度法在510 nm波长处测吸光度,分析不同石韦中的总黄酮含量。结果:不同种类、不同产地以及不同部位的石韦中总黄酮含量存在明显差异。结论:通过本实验对不同石韦中的总黄酮含量测定的分析,为石韦药材品种的鉴别和质量研究提供了一定的参考。

Objective To compare total flavone in different areas, different species and different extrac-tive fractions of Pyrrosia . Methods ： To extract with 60% ethyl alcohol then detect by UV - VIS spectro-photometry in 510 nm. Results： There are obvious differences of total flavone content in different species,different areas and different extract fractions of Pyrrosia . Conclusion： According to the analysis of totalflavone content in different Pyrrosia, some references were provided for the identification and research ofPyrrosia species.
