Noval Selective Ligand-Extraction of Bioactive Components in Complex Natural Products Applying Immobilized Multi-Target Magnetic Beads
Choerospondias axillaris is a medicinal plant used for treating coronary heart disease (CHD) due to its broad spectrum of anti-inflammatory activities. Cyclooxygenase 2 (COX-2) and lipoxygenase 5 (5-LOX) were immobilized on magnetic nanoparticles for selective ligand-extraction of these two enzymes present in C. axillaris. Sixteen extracted components were identified and analyzed using ultraperformance liquid chromatography plus Q-Exactive Orbitrap tandem mass spectrometry (UHPLC-Q-ExactiveOrbitrap-MS/MS), including flavonoids Curcumin and Epicatechin. The metabolization of the aforementioned 16 components in rats with acute blood stasis indicated a solid pharmacodynamic foundation. This method offers an effective approach for conducting basic research on the enrichment, analysis, and efficacy evaluation of active components in complex natural products.
期刊介绍：
Biomedical Chromatography is devoted to the publication of original papers on the applications of chromatography and allied techniques in the biological and medical sciences. Research papers and review articles cover the methods and techniques relevant to the separation, identification and determination of substances in biochemistry, biotechnology, molecular biology, cell biology, clinical chemistry, pharmacology and related disciplines. These include the analysis of body fluids, cells and tissues, purification of biologically important compounds, pharmaco-kinetics and sequencing methods using HPLC, GC, HPLC-MS, TLC, paper chromatography, affinity chromatography, gel filtration, electrophoresis and related techniques.
