Objective To establish HPLC fingerprints of Saussurea involucrata for the quick quality control. Methods Chlorogenic acid, syringin, rutin, luteolin, and apigenin were used as reference substances. DiamonsilTM C18(250 mm×4.6 mm, 5 μm) column was used and the methanol-water (0.8% acetic acid, 0.2% triethylamine, pH 3.5—4.0) was chosen as a mobile phase. The column temperature was 30 ℃ and the fingerprint was detected at 270 nm. The detection time was 30 min, and the flow rate was 1.0 mL/min. Ten batches of S. involucrata samples from various habitats were anlayzed to establish a reference fingerprint. Results Thirteen characteristic peaks were indicated on HPLC fingerprints. Conclusion This method is simple and accurate with a good reproducibility and provides a reference standard for the quality control of S. involucrata.
