Abstract:
To establish the quality control methods for the standard decoction of Ephedrae Herba, and provide the reference for quality evaluation method of all Chinese herbal medicine decoction.Standard decoction of Ephedrae Herba was prepared, and UPLC-UV fingerprint was established to determine the total contents of ephedrine and pseudoephedrine. Then UPLC-QTOF/MS was used to confirm the major common peaks in the fingerprint to clarify the main chemical constituents in the decoction. In addition, the stability of the process was evaluated by calculating the parameters such as the extraction ratio, transfer rate of the index components and the pH values.In the decoction of Ephedrae Herba, the total average concentration of ephedrine and pseudoephedrine was (2.11±0.70) g•L⁻¹; the similarities of all the fingerprints were more than 0.85; there were 10 major common peaks in the fingerprint, including alkaloids, flavonoids and organic acids; the extraction ratio was (17±3.2)%, and the overall transfer rate of ephedrine and pseudoephedrine was (32.4±8.1)%.The method for evaluating the quality of standard decoction of Ephedrae Herba was established in this article, providing reference for the quality control of products which were stemmed from the water extract of Ephedrae Herba.
