OBJECTIVE To establish the characteristic map and multi-component content determination method of Huangbaiyi Lung Drink, and to study the purification process of the extract by ceramic membrane ultrafiltration technology, and to establish a purification and refining method for the extraction of Huangbaiyi Lung Drinking Water suitable for industrial production. METHODS HPLC was used to establish the characteristic map of Huangbaiyi Lung Drink, combined with chemical pattern recognition to screen the differential components, and the orthogonal design experiment L9(34) was used to optimize the optimal ultrafiltration process parameters of Huangbaiyi Lung Drinking Water extract with the identification components, the retention rate of total polysaccharides and alcohol extracts and the impurity removal rate were the process evaluation indexes. RESULTS There were 19 common peaks in the characteristic map, 4 components such as chlorogenic acid, and 11 differential components such as verbascoside isoflavone glucoside were screened. The optimal ultrafiltration process conditions were as follows: membrane pore size of 20 nm, operating pressure of 0.12 MPa, feed liquid temperature of 20 ℃, cross-flow velocity of membrane surface of 4.6 m·s-1, the retention rates of total polysaccharides, ethanol extracts, chlorogenic acid, verbasyl isoflavone glucoside, glycyrrhizin and rutin were 82.86%, 84.23%, 92.97%, 92.54%, 92.92% and 92.29%, respectively, and the impurity removal rate was 11.73%. CONCLUSION The established method for the determination of multi-component content is reliable, and the selected ultrafiltration refining process has low production cost, good safety and high repeatability, and has a good prospect for industrial production, which can provide a reference for the refining of aqueous extract of traditional Chinese medicine compounds.
