Objective To establish and compare HPLC fingerprint chromatograms of Dipsaci Radix decoction pieces, aqueous decoction and formula granules.Methods The HPLC analysis was carried out in Wondasil C18 column (4.6 mm × 250 mm, 5 μm) with a mobile phase of acetonitrile-0.1% phosphoric acid by gradient elution. The flow rate was 1.0 mL/min; the detection wavelength was set at 212 nm; the column temperature was kept at 30℃. Results The fingerprint chromatograms from 12 batches of Dipsaci Radix decoction pieces, aqueous decoction and formula granules were established respectively. 14 common peaks in the fingerprint chromatogram in the formula granules could be tracked in the aqueous decoction, and 13 common peaks in the fingerprint chromatogram could be tracked in the decoction pieces. 2 chemical compounds were identified, such as asperosaponinⅥ and chlorogenic acid.ConclusionThe method of HPLC fingerprint chromatograms is stable and with good repeatability. Dipsaci Radix decoction pieces, aqueous decoction and formula granules are basically the same chemical composition.
