Figure 1. — HPLC fingerprint analysis of YQYYT decoction. The HPLC system was equipped with an Agilent HP-1100 HPLC instrument. Separation was performed on an Agilent TC-18 (4.6×250 mm, 5 µm) analytical column with mobile phase consisting of acetonitrile and water with gradient elution at a flow rate of 0.6 ml/min and the column temperature at 25°C. The UV wavelength used for detection was set at 203 nm, and the analysis time was 50 min. A total of 38 common peaks for YQYYT were identified in the HPLC fingerprint analysis. HPLC, high performance liquid chromatography; YQYYT, yi-qi-yang-yin-tang.
