NMRLiquid chromatography–solid phase extraction–nuclear magnetic resonance (HPLC-SPE-NMR), noveland highly promising hyphenated technique which is based on post-column analyte trapping by solidphaseextraction. The analytes are subsequently eluted from the SPE cartridges using deuteratedsolvents. This ...
南非钩麻Harpagophytum procumbens(Burch.)DC.eX.Meissn的次生根作为植物饮食补充剂或治疗炎症、风湿的天然药物被广泛使用。其根的极性成分已广泛研究,但非极性成分几乎无人关注。作者应用高效液相色谱法-固定相萃取-核磁共振(HPLC—SPE—NMR)快速分离鉴定了该植物石油醚粗提物中新的、不稳定的chinane型三环二萜类化合...
This review describes the principles and performance of a novel and highly promising hyphenated technique, HPLC-SPE-NMR, which is based on post-column analyte trapping by solid-phase extraction. The analytes are subsequently eluted from the SPE cartridges using deuterated solvents. This indirect HPLC...
A bioanalytical platform combining magnetic ligand fishing for α-glucosidase inhibition profiling and HPLC-HRMS-SPE-NMR for structural identification of α-glucosidase inhibitory ligands, both directly from crude plant extracts, is presented. Magnetic beads with N-terminus-coupled α-glucosidase were synth...
