360 JOURNAL OF COSMETIC SCIENCE CONCLUSION In this work, an MSPE met hod was dev eloped for pre-concentration of allura red for de- termination by HPLC. The sorbent was prepared by functionalizing choline proline ionic liquid on Fe3O4@SiO2. The method had simple operation steps, short extraction process time, and high extraction effi ciency. This method was used to determine the content of allura red in lipsticks, with high sensitivity and good accuracy.
