ABSTRACT
To establish the HPLC fingerprints of Eucommia ulmoides at different ages of different varieties with pi-noresinol diglucoside as the reference material to provide the basis for the HPLC fingerprints in the enterprise quality standards of Eu-commia ulmoides from the GAP base of Chenzhou Dacheng Chinese Herbal Medicine Co. Ltd. . Methods: A column of ZORBAX E-clipse XDB-C18 (250 mm × 4. 6 mm, 5μm) was used. The mobile phase consisted of methanol-0. 1% phosphoric acid with gradient e-lusion. The detection wavelength was 277 nm, the column temperature was 25℃,the flow rate was 1. 0 ml·min-1 , and the injection volume was 5 μl. Results:The Eucommia ulmoides HPLC fingerprints including 14 common peaks were established with pinoresinol diglucoside as the reference material. The similarity of the HPLC fingerprints of 10 samples was over 0. 939. Conclusion:The method is accurate and reliable. The HPLC fingerprints can be used as the enterprise quality standards of Eucommia ulmoides for Chenzhou Dacheng Chinese Herbal Medicine Co. Ltd. .
