ABSTRACT
<p><b>OBJECTIVE</b>To establish a fingerprint analysis method of Qingfengtong capsule by HPLC.</p><p><b>METHOD</b>The samples were extracted with 70% ethanol in an ultrasonic bath. The extracts were analyzed at 35 degrees C on a Diamonsil C18 column (4.6 mm x 250 mm, 5 microm) with 0.1 mol x L(-1) potassium dihydrogen phosphate water-solution as mobile phase A, and methanol as mobile phase B. The analysis followed a linear gradient elution program. Initial condition of the mobile phase was 10% B for 2 minutes; then changed to 90% B in 40 minutes. The flow rate was kept at 1.0 ml x min(-1) and the detector wavelength was 262 nm.</p><p><b>RESULT</b>The main peaks in fingerprint chromatogram of Qingfengtong capsules were separated fairly well. The results of method validation meet the requirements for the fingerprints.</p><p><b>CONCLUSION</b>The established method can be used for the quality control of Qingfengtong capsules.</p>
