| titleOfInvention | Choline-proline ionic liquid modified magnetic nanomaterials and its detection method for aprelate combined with HPLC |
| abstract | The invention belongs to the field of drug analysis, and discloses a choline-proline ionic liquid modified magnetic nanometer material and a method for detecting aprelate combined with HPLC. Choline-proline ionic liquid [Ch][Pro] was modified to the surface of Fe 3 O 4 @SiO 2 by cross-linking agent 1,6-hexamethylene diisocyanate (HDI), and the material was used to extract love in actual samples. Plet, and combined with high performance liquid chromatography-ultraviolet detector to determine its content. The results show that: Fe 3 O 4 @SiO 2 @HDI@[Ch][Pro] nanoparticles can quickly adsorb aprelide, and the extraction rate of aprelide in actual samples can reach more than 96%. The limit is 2.0ng mL ‑1 , the linear range is 0.01‑20 μg mL ‑1 , and the enrichment factor is 13. The method was successfully applied to the determination of aprelide in tablets and serum samples. |
