Ultra-high-performance liquid chromatography high-resolution mass spectrometry (UHPLC-HRMS) variants currently represent the best tools to tackle the challenges of complexity and lack of comprehensive coverage of the metabolome. UHPLC offers flexible and efficient separation coupled with high-sensitivity detection via HRMS, allowing for the detection and identification of a broad range of metabolites. Here we discuss current common strategies for UHPLC-HRMS-based metabolomics, with a focus on expanding metabolome coverage.

Polysorbate 20 (PS20) is one of the most commonly used non-ionic surfactants in cosmetics, pharmaceuticals and food products. Considered as biocompatible and non-irritating, it is further valued for its solubilising and protein stabilising properties. PS20 is manufactured through a multi-stage reaction of sorbitol with various fatty acids and ethylene oxide, resulting in a complex mixture of components with different molecular weights and polarity.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.

Chili peppers have been under the spotlight of bioactivity research as they feature a diverse and rich phytochemical profile with multiple health promoting effects. These beneficial properties are related to the chemical composition of chili peppers and is of utmost importance to identify varieties with the strongest bioprospecting potential. In this study, 19 chili pepper varieties were investigated originating from Capsicum annuum L.

Background And Purpose: Ciprofol, a novel intravenous anesthetic, has been shown to exert protective effects against ischemic stroke, a leading cause of death and disability; however, its molecular mechanisms remain unclear. This study aimed to explore the molecular mechanisms underlying the neuroprotective effects of ciprofol using metabolomics.
Methods: This study used a middle cerebral artery occlusion (MCAO) rat model to simulate cerebral ischemia-reperfusion injury (CIRI).

Amphenmulin is a novel pleuromutilin derivative with proven excellent antibacterial activity. To investigate its metabolism in animals, ultra-high-performance liquid chromatography coupled with quadrupole/time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS) was employed to analyze and identify metabolites in rats and chickens and using human, rat, pig, chicken and beagle dog liver microsomes. We identified 18 metabolites from liver microsomes and 24 and 17 metabolites for rats and chickens, respectively.
