Two imidazolium supported ionic liquid phases (SILPs) containing different anions, trifluoromethanesulphonate [CF(3)SO(3)(-)], and tetrafluoroborate [BF(4)(-)], were synthesized and evaluated as solid-phase extraction sorbents for extracting acidic pharmaceuticals from aqueous samples under strong anion-exchange conditions, which include an effective cleanup of the sample. The best SILP material [MI(+)][CF(3)SO(3)(-) ] was selected and successfully applied to the determination of acidic pharmaceuticals in different types of water samples (river water and effluent wastewater). The results were then compared to the previously synthesized SILP material based on [MI(+)][CF(3)COO(-)] and the commercially available Oasis MAX sorbent.

Introduction: As a widely used Chinese herbal medicine, Mume Fructus pulp (MFP) has rich nutritional value and biological activity, but its quality control research is relatively scarce.
Objectives: The objective of the study was to evaluate the quality difference between MFPs from different origins and its adulterant apricot pulp (APP), and to identify potential quality markers.
Methods: The chemical compositions were identified by untargeted metabolomics analysis based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry combined with feature-based molecular networking.

Severe corneal injuries can cause visual impairment even blindness. Surgically stitching or implanting biomaterials have been developed, but their implementation requires professional surgeons, failing to address the immediate need of medical treatment. The pressing challenge lies in developing multifunctional biomaterials that enable self-management of corneal injuries.
