    Journal: Zhongguo Zhong Yao Za Zhi; 2006 Jun; 31(12):972-4. PubMed ID: 17048640.
    Abstract:
    OBJECTIVE: To establish the HPLC fingerprint of Rhizoma Polygoni Cuspidati (Polygonum cuspidatum). METHOD: The HPLC separation was carried with Diamonsil C18 column and eluted with a gradient from methanol and 0.1% phosphoric acid, the detection wavelength was at 230 nm and recording 70 min. The similarity of chromatograms was compared by mean of the software from Zhongnan University. RESULT: The constituents of P. cuspidatum were well separated by HPLC, and the similarity was above 0.80. CONCLUSION: The method can be used for the study of fingerprints of Rhizoma Polygoni Cuspidati.
