This invention discloses a method for refining and desalting belladonna fluid extract, relating to the field of traditional Chinese medicine pharmaceuticals. Belladonna grass is pulverized through a 24-mesh sieve to form coarse powder. The powder is percolated using ethanol as a solvent to obtain a primary belladonna extract. The ethanol is recovered from the primary extract, and the extract is cooled to room temperature. Chlorophyll is removed by separation using a ceramic membrane. The extract is then filtered, and the filtrate is concentrated using an organic nanofiltration membrane to remove salts. The membrane filtrate is further concentrated under reduced pressure to a thick paste. Seven times the volume of ethanol is added and stirred until homogeneous. The mixture is allowed to stand until complete precipitation. The supernatant is collected, and the ethanol is recovered and concentrated to a thick paste. Based on the content determined in the thick paste, an appropriate amount of 85% ethanol is added, and the mixture is diluted with water to prepare a finished belladonna fluid extract product conforming to pharmacopoeia standards. This method is stable and reliable, avoids high-temperature degradation of the active ingredients, effectively removes impurities from the belladonna fluid extract, and prevents salt precipitation in the finished product. This ensures its efficacy and medication safety, and has broad market application prospects.
