摘要： 目的比较款冬花药用和非药用部位中6种活性成分含量差异。方法建立高效液相色谱法同时测定款冬花不同部位中绿原酸、芦丁、3,4-O-二咖啡酰奎宁酸、3,5-O-二咖啡酰奎宁酸、4,5-O-二咖啡酰奎宁酸、款冬酮等6种成分的含量。采用ShimNex CS C18（4.6 mm×250 mm, 5 μm）色谱柱,流动相为乙腈-0.1%磷酸水溶液,梯度洗脱,检测波长为220 nm,流速为1 mL·min-1,柱温为30 ℃。结果芦丁和款冬酮在款冬花的花梗和根中均未检出,其余4种咖啡酰奎宁酸类成分也均低于花蕾。结论验证了款冬花药材以花蕾入药的科学性和合理性,非药用部位的混入会影响该药材质量,建议在质量标准中增加杂质检查项目,确保药材的质量。

Abstract: Objective To study the differences in contents of six active ingredients in medicinal and non-medicinal parts of Farfarae Flos. Methods A high-performance liquid chromatography method was established for simultaneous determination of six components, including chlorogenic acid, rutin, 3,4-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid, 4,5-O-dicaffeoylquinic acid, and tussilagone, in different parts of Farfarae Flos. The experiment was conducted using a ShimNex CS C18 (4.6 mm×250 mm, 5 μm) chromatographic column. The mobile phase was composed of acetonitrile-0.1% phosphoric acid aqueous solution under gradient elution. The detection wavelength was 220 nm at a flow rate of 1 mL·min-1 and the column temperature was 30℃. Results Rutin and tussilagone were not detected in the pedicels or roots of Farfarae Flos. The contents of other four caffeoylquinic acids were significantly lower than those in the buds. Conclusion The experiment has justified the use of buds of Farfarae Flos as the medicinal material. The mixture with non-medicinal parts will affect the quality of medicinal materials and should be avoided in the process of production. It is recommended that inspections of impurities be included in quality standards to ensure the quality of medicinal materials.
