Objective: To establish the chromatography fingerprint of Polygoni Cuspidati Rhizoma et Radix with hyphenated technique of HPLC-DAD-ELSD and to evaluate Polygoni Cuspidati Rhizoma et Radix from 10 different origins. Methods: Luna C18 (2) column (250 mm × 4.6 mm, 5 μm) was used. Mobile phase was acetonitrile-H2O; Flow speed was 1.0 mL/min; Temperature of column was set at 35℃; Detective wavelength was at 254 nm; Injection volume was 10 μL. The temperature of drift tube was 109℃ and the flow speed was 3.0 L/min. Results: The chromatography fingerprint of Polygoni Cuspidati Rhizoma et Radix from 10 different origins was established. In the chromatography fingerprint with HPLC-DAD of Polygoni Cuspidati Rhizoma et Radix, 19 common peaks were demarcated and the similarities of Polygoni Cuspidati Rhizoma et Radix were between 0.938-0.993. In the chromatography fingerprint with HPLC-ELSD of Polygoni Cuspidati Rhizoma et Radix, 14 common peaks were demarcated and the similarities of Polygoni Cuspidati Rhizoma et Radix were between 0.905-0.999. Polydatin, resveratrol, emodin-8-O-β-D-glucoside, physcion-8-O-β-D-glucoside, emodin, and physcion were identified. Conclusion: The method is accurate and stable, which can be used as the evidence for the quality evaluation of Polygoni Cuspidati Rhizoma et Radix. © 2015, Editorial Office of Chinese Traditional and Herbal Drugs.
