Schmidt等人通过LC-SPE-NMR/MS技术研究了LASS产品中LASS物种的表征。这种联用技术已成为表征药物代谢物和植物化学化合物的宝贵工具。在他们的工作中,通过使用高效液相色谱法将LASS物种分离成不同的组分,以解决Goon等人报告的问题,并通过1HNMR对技术LASS产品进行表征。使用柱后固相萃取的后续组分收集浓缩LASS异构体,与传统...

Liquid chromatography (LC)–solid-phase extraction (SPE)–nuclear magnetic resonance (NMR)–mass spectrometry (MS) coupling is a key technology for fast and thorough structure elucidation of valuable mass-limited samples. Laborious serial isolation and purification procedures of metabolites, byproducts or...
贯叶金丝桃提取物 活性成分 MS法 NMR SPE 鉴别 LC 间苯三酚类 [摘要] 贯叶金丝桃Hypericum perforatum提取物中的活性成分(酚酸类、黄酮类、萘并二蒽酮类和间苯三酚类)相当复杂,它们的含量受生态环境、生理和遗传等因素影响而变化,又因部分成分暴露于阳光时对氧化的敏感性和在空气下在溶剂中不稳定而产生转换和降...

NMR-profiling has successfully been applied to capture the food metabolome, with particular focus on gut microbiome-mediated metabolites. More sensitive and selective GC- and LC-MS profiling approaches have been developed to capture less abundant food metabolites. These MS-based profiling approaches ...
