Abstract: |
[Objective] To establish the HPLC/PDA/ELSD fingerprint of Rhizoma Anemarrhenae. [Methods] This experiment had been done on Waters Symmetry ShieldTM RP C18 (5 μm,4.6 mm×250 mm) analytical column of 30 ℃, with a gradient eluted acetonitrile-0.1% acetic acid mobile phase system of 1.0 mL/min. The detection wavelength had been set at 258 nm, N2 pressure was 30 Psi, and the temperature of the drift tube was 80 ℃. [Results] The mutual modes of the HPLC/PDA/ELSD fingerprint were set up under the established condition. The 17 mutual peaks in the HPLC-PDA fingerprint and 14 mutual peaks in the HPLC-ELSD fingerprint of 11 samples were confirmed. [Conclusion] The method that had been established in this experiment is a good method to totally control the quality of Rhizoma Anemarrhenae. |
