| titleOfInvention | Polymer continuous bed for online enriching and purifying ursolic acid and method for online enriching and purifying ursolic acid |
| abstract | The invention provides a polymer continuous bed for online enriching and purifying ursolic acid and an online enriching and purifying method for the ursolic acid. The preparation method is simple, the obtained polymer continuous bed for online enriching and purifying the ursolic acid has excellent specific surface area, pore structure and other performances, the acting force between the polymer continuous bed and the ursolic acid is increased, the ursolic acid can be effectively enriched online, the adsorption capacity is large, the detection limit is low, the precision, the sensitivity and the accuracy of analysis and detection are improved, the recovery rate is high, the operation steps of sample pretreatment are simplified, the pretreatment time of a sample is greatly shortened, the method is economical and practical, and simultaneously, the green chemistry is favorably realized. |
