Abstract:
Objective: To establish the fingerprint chromatogram of Tongguanteng Injection (caulis Marsdeniae Tenacissimae). Methods: HPLC with ZORBAX SB C 18 column was used, the (a) 0.05% H 3PO 4 H 2O and (b) ACN 0.05% H 3PO 4 H 2O (13∶87) (gradient elution) as a mobile phase and detection wavelength at 254nm. Results: 22 peaks were indicated on the HPLC fingerprint of Tongguanteng Injection. The relative retention time and relative peak area were obtained with itself peak at retention time 48.5 min. Conclusion: The method is simple and accurate with a good reproducibility and can be used as a quality control method for Tongguantent Injection.
