The flower bud of Tussilago farfara L., called Farfarae Flos, has traditionally been used in Oriental medicine for the treatment of bronchitis and asthma. To establish a standard for quality control as well as the reliable identification of Farfarae Flos, the contents of five standards, rutin (1), isoquercetin (2), 3,5-dicaffeoylquinic acid (3), tussilagone (4), and tussilagonone (5), were determined by quantitative high-performance liquid chromatography (HPLC)/photodiode array (PDA) analysis. The five standards were separated on a Young Jin Bio Chrom Aegispak C18-L (250-mm×4.6-mm, 5-μm) column by gradient elution using 0.03% trifluoroacetic acid in water (A), with acetonitrile (B) as the mobile phase. The flow rate was 1.0 mL/min, and the UV detector wavelength was set at 220 nm. The method was successfully used in the analysis of Farfarae Flos from different geographic origins with relatively simple conditions and procedures, and the results demonstrated satisfactory linearity, recovery, precision, accuracy, stability, and robustness. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of 62 Farfarae Flos samples. This result indicated that the established HPLC/PDA method is suitable for quantitation and pattern recognition analyses for the quality evaluation of Farfarae Flos.
