摘 要：目的：建立连翘药材中连翘苷的含量测定方法，比较不同产地连翘中连翘苷的含量。方法：采用反相高效液相色谱法测定不同产地连翘药材中连翘苷的含量，流动相为乙腈-水(25∶75)，流速为1.0mL•min-1，检测波长为277nm，进样量为10μL，柱温为30℃。结果：在选定色谱条件下，连翘苷分离度良好，线性范围为0.4348～4.348μg,r=0.9999，平均回收率98.9%，RSD=0.68%(n=6)；不同产地连翘药材中连翘苷含量差异较大，其中陕西洛南，湖北邵县以及四川成都的连翘药材中连翘苷含量相对高于其它产地。结论：该方法测定连翘中连翘苷的含量，简单、灵敏、准确、重现性好，连翘苷在各产地连翘间差异较大。

Abstract:Objective: To develop a method for determining the content of phillyrin in Fructus Forsythiae and to compare the content in Fructus Forsythiae from different habitats. Methods:HPLC was adopted to determine the content of phillyrin, the mobile phase was acetonitrile-water(25∶75),the velocity was 1.0 mL•min-1, the UV detection wavelength was 277nm, the sampling volume was 10mL, the temperature of column was 30℃. Results: Under the selected Chromatography condition the phillyrin was observed in a good separation degree, a good linear with range of 0.4348~4.348μg, r=0.9999, the average recovery was 98.9% and RSD was 0.68%(n=6). The content of phillyrin in Fructus Forsythiae from different habitats is different, of which the content of phillyrin in Fructus Forsythiae from Luonan(Shaanxi), Shaoxian(Hubei) and Chengdu(Sichuan) are higher than that of others.Conclusion:The method is simple, sensitive, accurate and with good reproducibility. It can be used to determine the content of phillyrin in Fructus Forsythiae. The content is different with the habitat of Fructus Forsythiae.
