Abstract:
Objective:To establish a quality control method for the standard decoction of Polygoni Avicularis Herba.Methods:Totally 12 batches of decoction pieces from different origins were collected, the standard decoction was prepared and the quality evaluation method was established, the content of index components in the decoction pieces and the standard decoction was determined with HPLC, the index components, solution pH and other parameters were calculated, and the similarity analysis was carried out against the fingerprints.Results:The total content of myricetin in 12 batches of decoction pieces was >0.12%, and the content of myricetin in the standard decoction was >0.03%, which met the standard of the 2020 edition of the Chinese Pharmacopoeia. The pH value was 5.1-5.5, the transfer rate of myricetin components ranged from 50.0%-106.3%, and the fingerprint study showed that there were 7 common peaks. The similarity analysis results indicated that the standard decoction of 12 batches of decoction pieces of Polygoni Avicularis Herba had good consistency.Conclusion:The preparation process is stable and feasible in line with the traditional decoction preparation method, and can be used for the research and quality evaluation of the standard decoction.
