| Abstract: | Objective: To establish a method for preparing a large amount of high-purity neobaicalein. Methods: The extraction of neobaicalein from Scutellaria baicalensis by ultrasonic method and reflux extraction method were compared, and the effect of different extraction solvents on the yield of neobaicalein from S. baicalensis was investigated. The content of neobaicalein was determined by HPLC, and neobaicalein was prepared by LC-8A high-pressure preparative chromatograph. Results: When reflux extraction was adopted and ether were used as extraction solvent, the yield of neobaicalein was the highest, and the purity of neobaicalein was 97.96%. Conclusion: The method established in this experiment is easy to operate and has good reproducibility. And the purity of the prepared neobaicalein mets the requirements of the reference substance. |
