Abstract:
Objective: To prepare standard decoction of Alismatis Rhizoma (AR) and establish its quality evaluation system, and provide reference for the development of dispensing granules of AR. Methods: A total of 18 batches of AR decoction pieces were collected to prepare standard decoction of AR according to the standard process. Quality evaluation system of standard decoction of AR was established with pH value, dry extract rate, fingerprint similarity and transfer rate of alisol B 23-acetate as indexes. Results: The mass fraction of alisol B 23-acetate in AR decoction pieces was 0.057%—0.267% with the average value of 0.156%, water content was 9.2%—12.8% with the average value of 10.44%; the pH value of standard decoction of AR was 4.11—5.60, dry extract rate was 10.25%—17.09%; transfer rate of alisol B 23-acetate from decoction pieces to standard decoction was 10.49%—17.49%. Conclusion: The established quality evaluation method is stable and feasible, which is suitable for the development and quality evaluation of standard decoction of AR, which can provide reference for the development of dispensing granules of AR and related classic formulas.
