Abstract:
Objective:To establish the fingerprint analysis method for the aqueous extracts of Eucommia ulmoides from Enshi by HPLC. Methods:The fingerprint of aqueous extracts of ten batches of Eucommia ulmoides from Enshi were analyzed by HPLC. The columnwasWondaSilC18(250mm×4.6mm,5μm). Themobilephaseconsistedofacetonitrile-0.1% phosphoricacidwithgradient elution. The flow rate was 1. 0 ml·min-1 , the detection wavelength was 230 nm, the column temperature was 25℃, and the injection volume was 10 μl. Results:The fingerprint consisted of 12 common peaks. The similarity range of ten batches of Eucommia ulmoides calculated by similarity evaluation system for the chromatographic fingerprint of TCM(Version 2004 A)was 0. 596-0. 997. The standard fingerprint of Eucommia ulmoides was established by HPLC. Conclusion: The established HPLC fingerprint analysis method for Eu-commia ulmoides from Enshi is simple, stable and reproducible, which can effectively control the quality of Eucommia ulmoides from Enshi.
