Determining Wine Authenticity: A Metabolomics Analysis Using UHPLC ESI/Q-TOF MS Authors
This application note demonstrates the advantages of using an Agilent 1290 Infinity LC system combined with the Agilent 6530 Q-TOF LC/MS and multivariate statistical analysis for metabolic profiling of wines. This resulted in the differentiation of wines from different geographical areas including France and China, and it potentially allows for the identification of wine biomarkers. Introductio...
متن کاملIdentification of Proanthocyanidins from Litchi (Litchi chinensis Sonn.) Pulp by LC-ESI-Q-TOF-MS and Their Antioxidant Activity
Content of total proanthocyanidins as well as total phenolics, flavonoids, antioxidant activities were evaluated for litchi (Litchi chinensis Sonn.) pulp of 32 cultivars. One cultivar, Hemaoli, showed the highest total proanthocyanidins and total phenolics, and DPPH or ABTS radical scavenging activities. ESI-MS and NMR analysis of the Hemaoli pulp crude extracts (HPCE) showed that procyandins c...
متن کاملUHPLC-ESI Accurate-Mass Q-TOF MS/MS Approaches for Characterizing the Metabolism and Bioavailability of Quercetin in Humans
The bioflavonoid quercetin occurs as a range of glycosides in foods, and the composition of these glycosides is species and cultivar specific. In humans, quercetin undergoes extensive phase II biotransformation, resulting in a complex mixture of metabolites. The bioactivity of the individual metabolites depends on the type and position of the conjugates formed during biotransformation. An Agile...
متن کاملUHPLC-PDA-ESI/HRMSn Profiling Method To Identify and Quantify Oligomeric Proanthocyanidins in Plant Products
Oligomeric proanthocyanidins were successfully identified by UHPLC-PDA-HRMS(n) in a selection of plant-derived materials (jujube fruit, Fuji apple, fruit pericarps of litchi and mangosteen, dark chocolate, and grape seed and cranberry extracts). The identities of 247 proanthocyanidins were theoretically predicted by computing high-accuracy masses based on the degree of polymerization, flavan-3-...
متن کاملQuantification of rutin in rat's brain by UHPLC/ESI-Q-TOF-MS/MS after intranasal administration of rutin loaded chitosan nanoparticles
Rutin (RT), an antioxidant drug, has been utilized to treat cerebral ischemia hence a sensitive quantification method for estimation of RT in brain homogenate is necessary to develop. This study aims to prepare RT loaded Chitosan Nanoparticles (RT-CS-NPs) develop and validate ultra-high performance liquid chromatography-electrospray ionization-synapt mass spectrometric method Synapt Mass Spectr...
