Abstract A method for the comprehensive profiling of intact glucosinolates (GLSs), major and minor, occurring in leaves seeds rocket salad ( Eruca sativa L.) is presented using optimized reversed‐phase liquid chromatography (RP‐LC) with electrospray ionization (ESI) ion trap mass spectrometry (ITMS). ESI‐ITMS negative mode was confirmed to be very suitable analyze these compounds crude extracts. After extraction from plant material methanol/water (70:30 v/v) at 70°C, analytes interest were...
We describe a chromatographic method that uses isocratic elution and pulsed amperometric detection to determine soluble carbohydrates in plant tissues. Such provides rapid convenient means obtain complete profile of the sugar components leaves roots from olive (Olea europaea L. cv. Coratina) plants. A simple purification extracts using pure water was developed, which is far less time-consuming retains high level accuracy. Excellent separation myo-inositol, galactinol, mannitol, galactose,...
The superbasic proton sponge 1,8-bis(tripyrrolidinylphosphazenyl)naphthalene (TPPN) has been successfully employed for the structural characterization of neutral saccharides, cyclodextrins, and saccharide alditols by matrix assisted laser desorption/ionization tandem mass spectrometry (MALDI-MS/MS). Owing to its inherently high basicity, TPPN is capable deprotonating carbohydrates (M) providing an efficient simple way produce gas-phase [M - H]- ions. Highly informative negative ions MS/MS...
Nitrate and nitrite as sodium or potassium salts are usually added to meat products develop the characteristic flavor, inhibit growth of microorganisms (particularly Clostridium botulinum), effectively control rancidity by inhibiting lipid oxidation. However, both nitrate ions need be monitored for ensuring quality safety cured meats. In this work, first time content in homogenized samples baby foods was determined a validated method based on ion chromatography (IC) coupled with conductivity...
Hydrophilic interaction liquid chromatography (HILIC) and electrospray ionization (ESI) coupled to either Fourier-transform (FT) orbital-trap or linear ion-trap tandem mass spectrometry (LIT-MS/MS) was used characterize the phospholipidome of yellow lupin (Lupinus luteus) seeds. Phosphatidylcholines (PC) were most abundant species (41 ± 6%), which followed by lyso-forms LPC (30 11%), phosphatidylethanolamines (PE, 13 4%), phosphatidylglycerols (PG, 5.1 1.7%), phosphatidic acids (PA, 4.9...
Abstract Steroidal glycoalkaloids (SGAs) extracted from tomato leaves and berries ( Lycopersicon esculentum Mill.) were separated identified using optimized reversed‐phase liquid chromatography with electrospray ionization (ESI) ion trap mass spectrometry (ITMS). The ESI source polarity chromatographic conditions evaluated. spectra contain valuable information, which includes the of SGAs, aglycones, several characteristic fragment ions. Cleavage at interglycosidic bonds proximal to aglycones...
Abstract Many metabolomic applications use gas chromatography/mass spectrometry (GC/MS) under standard 70 eV electron ionization (EI) parameters. However, the abundance of molecular ions is often extremely low, impeding calculation elemental compositions for identification unknown compounds. On changing beam‐steering voltage ion source, relative abundances at EI were increased up to ten‐fold alkanes, fatty acid methyl esters and trimethylsilylated metabolites, concomitant with 2‐fold...
An approach is presented that can be of general applicability for structural elucidation naturally occurring glucosinolates (GLSs) in crude plant extracts based on the fragmentation isotopic A and + 2 peaks. The most important pathways were studied by tandem mass spectrometry (MSn, n = 2, 3) using a linear quadrupole ion trap (LTQ) upon GLSs separation optimized reversed-phase liquid chromatography (RPLC) electrospray ionization (ESI) negative mode. As LTQ MS analyzer ensures high...
The phospholipidome of blood microparticles (MPs) obtained from platelet-rich plasma healthy individuals was characterized by hydrophilic interaction liquid chromatography (HILIC) coupled to electrospray ionization tandem mass spectrometry (ESI-MS/MS). HILIC separation, performed on a silica stationary phase using an acetonitrile/methanol gradient, enabled the separation several phospholipids (PL) classes, viz., phosphatidyl-cholines (PCs), -ethanolamines (PEs), -serines (PSs), -inositoles...
