Metabolomics offers a unique approach to study biological systems. Liquid chromatography coupled mass spectrometry serves as powerful analytical tool analyze complex mixtures of metabolites. However, successful metabolomic analysis relies on sample preparation. While untargeted traditionally favors non-selective procedures like liquid-liquid extraction (LLE), these methods can compromise performance due limited analyte enrichment and potential matrix interferences. Solid-phase (SPE) has emerged well-established versatile technique for this purpose, offering advantages over other traditional LLE. This review explores the applications SPE solid-phase microextraction (SPME) in LC-MS-based metabolomics. We discuss various modes SPE, ranging from conventional flow-through cartridges plates approaches involving dispersion sorbent sample, well sorbents, their properties, diverse geometries support materials employed SPME. underscores emerging protocols further accelerate metabolomics research.

Application of Response Surface Methodology to Design and Optimize Purification of Acetone or Aqueous Acetone Extracts of Hop Cones (Humulus lupulus L.) Using Superparamagnetic Iron Oxide Nanoparticles for Xanthohumol Isolation

Materials, Journal Year: 2024, Volume and Issue: 17(19), P. 4827 - 4827

Published: Sept. 30, 2024

Iron oxide nanoparticles (IONPs) are an ideal sorbent for magnetic dispersion extraction due to their superparamagnetic properties and developed active surface. This work aims use IONPs, obtained by chemical co-precipitation, purify 100% acetone 50% extracts from hop cones (Humulus lupulus L.) ultrasonic-assisted solvent extraction. The were purified bitter acids (i.e., humulones, lupulones) isolate xanthohumol. sorption conditions optimized depending on the composition of mixture, specifically mass IONPs time needed achieve effective using response surface methodology (RSM). An analysis variance (ANOVA) was performed assess adequacy model, a good agreement found between experimental data proposed model. polynomial equation describing model is highly significant (p < 0.05), with precision Adeq (above 4). indicates usefulness regression prediction in design. final products purification contain 40.58 ± 2.84 µg mL-1 57.64 0.83 xanthohumol, respectively. extract provides more favorable smaller amount required higher recovery development reliable multivariate allowed optimization process, resulting high-purity xanthohumol natural sources.

A sensory granular material based on impregnated composite «cross-linked polyvinyl alcohol – magnetite» for the determination of carbohydrates by optical micrometry

Industrial laboratory Diagnostics of materials, Journal Year: 2024, Volume and Issue: 90(6), P. 5 - 14

Published: June 21, 2024

Synthesis and application of a composite material «cross-linked polyvinyl alcohol (PVA) – magnetite» as sensitive element for the determination carbohydrates by optical micrometry has been studied. The chemical structure was confirmed IR-spectroscopy. content Fe 3 O 4 in PVA granules calculated using magnetization curves. It is shown that introduction particles into at pH value buffer solution 6.8 significantly narrows range carbohydrate concentrations to be determined reduces sensitivity them. However, 8.6 presence does not affect metrological characteristics glucose fructose (their detection limit equals 7.9 mmol/dm ) but relative standard deviation their wt.%. Sensory with optimal magnetite (1.54%) were tested total natural syrups high level micrometry. results obtained match accepted reference values specified syrup manufacturers.
