不同产地款冬花药材质量比较研究

Comprehensive Quality Evaluation of Flos Farfarae from Different Habitats

目的比较不同产地款冬花药材的质量,为款冬花的利用和开发提供依据。方法采用高效液相色谱法测定不同产地款冬花中芦丁和款冬酮的含量,称量记录百蕾干重和蕾色,并对各项指标进行统计分析。结果不同产地款冬花中芦丁、款冬酮含量及百蕾干重存在显著差异,且芦丁和款冬酮含量存在显著正相关。主成分和因子分析表明,山西榆社、宁武、广灵的款冬花质量较优。结论不同产地款冬花药材质量存在差异,山西榆社、宁武、广灵的野生款冬花可作为优质种源。

Objective To compare the quality of Flos Farfarae from different habitats, and provide basis for the utilization and development of Tussilago farfara. Methods The contents of rutin and tussilagone were determinated by HPLC, the lO0-bud dry weight and bud color were weighed and observed. And the data of different samples were compared and statistical analysed. Results The content of rutin, tussilagone and 100-bud dry weight in Flos Farfarae from different place has a significant difference, and there was a significant positive correlation between rutin and tussilagone. Principal component and factor analysis showed that the quality of Flos Farfarae from Yushe, Ningwu, Guangling was better than other areas. Conclusion The quality of Flos Farfarae from different areas is difference, and wild T. farfara in Yushe, Ningwu, Guangling could be used as high quality germplasm.
