Objective: To establish the high performance liquid chromatography-fingerprint of Yunvjian. Methods: The method was established on a C18column( 250 mm × 4. 6 mm,5 μm),and the column temperature was 30 ℃. The mobile phase consisted of 0. 2%aqueous phosphoric acid-methanol in gradient elution and the flow rate was 1. 0 m L / min. The detection wavelength was 254 nm. Results: HPLC fingerprint of Yunvjian was established,and 17 characteristic peaks were contained in Yunvjian fingerprint. The peak5 was 5-hydroxy methyl furfural,peak 11 was mangiferin,peak 12 was verbascoside,peak 13 was ecdysterone,and peak 17 was methylophiopogonanone A. Conclusion: The method provides experimental evidence and logical proofs for determination of the effective components of Yunvjian.
