Abstract
Objective: To develop the fingerprint of Marsdenia tenacissima by UV-HPLC. Method: The RP-HPLC was performed on a Sinochrom ODS-BP column (4.6 mm×250 mm
5 μm). The mobile phase consisted of acetonitrile-0.1% H3PO4 with gradient elution. The fingerprint was detected at 223 nm. Result: The mutual mode of HPLC-UV specific chromatogram was set up. 14 common peaks were observed on the fingerprints of M. tenacissima
and the second peak was tenacissoside A. Conclusion: This method is simple and fast
thus it may be used for the fingerprint of M. tenacissima. It may also qualitatively and quantitatively reflect the content variation of the main ingredients in crude drugs
which would be helpful to improve the quality control level.
