The 3-hydroxy-3-methylglutaryl neohesperidosides of hesperetin (brutieridin, 1) and naringenin (melitidin, 2) were isolated detected from the fruits bergamot (Citrus bergamia). structures these compounds determined by spectroscopic chemical methods.
We report a novel highly crystalline MOF, featuring hydroxyl-decorated channels, capable of distinctly organizing guest organic molecules within its pores.
Food safety represents one of the main issues national and international agencies appointed to health control. In April 2003, a French agency disclosed that powdered or smashed hot chili pepper imported from India Pakistan was heavily contaminated with carcinogenic azo dye known as Sudan I. This paper deals modern approach for assaying content this colorant in foodstuff down limit few tens parts per billion. The isotope dilution method combined APCI tandem mass spectrometry used. internal...
Abstract The exact chemical structure of non–crystallising natural products is still one the main challenges in Natural Sciences. Despite tremendous advances total synthesis, absolute structural determination a myriad with very sensitive functionalities remains undone. Here, we show that metal–organic framework (MOF) alcohol–containing arms and adsorbed water, enables selective hydrolysis glycosyl bonds, supramolecular order so–formed chiral fragments organic by single–crystal X–ray...
A new method for a fast molecular profiling of olive oil unsaponifiable fraction has been developed. This approach, based on paper spray mass spectrometry, allows obtaining MS data with only few minutes analysis and without significant solvent disposable consumption. Tandem spectrometry high-resolution experiments have performed to identify the main ions detected. The coming from analyses sixty-three samples three different categories: extra virgin (EVOO), (VOO), pomace (POO), used test...
A high-throughput mass spectrometric method is presented for the simultaneous detection of Sudan I, II, III, IV, and Para-Red azodyes in foodstuff. The based on use deuterium-labeled internal standards atmospheric pressure chemical ionization (APCI) a triple-quadrupole instrument. gas-phase breakdown pattern each labeled unlabeled analogue displays naphthoic moiety as common fragment. search parents this species (parent ion scans) allows, by flow injection single run, evaluation presence...

The based on use paper spray spectrometry (MS) deuterium‐labeled internal standards a triple‐quadrupole instrument. detailed assay each azo‐dye was performed by isotope dilution method, through precursor ion scan approach, using standards. gas‐phase breakdown pattern labeled unlabeled analogue displays naphthoic moiety as common fragment. dyes...
Fish parvalbumin (PRVB) is an abundant and stable protein in fish meat.
Clementine is a citrus fruit that has found peculiar habitat in specific areas of Calabria, region located southern Italy. Due to its characteristics it was recently awarded with protected geographical indications (PGI) from the European Union. In this work, stepwise linear discriminant analysis (S-LDA), soft independent modeling class analogy (SIMCA), and partial least-squares (PLS-DA) were used build chemometric models able protect PGI others different origin. Accordingly, concentration...
A simple procedure is proposed for selective protein solubilization and trypsin digestion, followed by off-line liquid chromatography–matrix assisted laser desorption ionization mass spectrometry (LC–MALDI MS) analysis of Oenococcus oeni (O. oeni) bacterium. Peptides were identified from tryptic digests using sequencing tandem database searches. Cytoplasmic membrane related proteins (MRP) in the O. MS/MS data points out 13 peptides having one point mutation 9 proteins. The major...
Herein we describe a rapid, simple, and reliable method for the quantitative analysis molecular species fingerprinting of saffron (Crocus sativus L.) by direct MS MS/MS analysis. Experimentally, powdered was subjected to brief treatment with 0.3% TFA water/acetonitrile solution, resulting mixture directly placed on MALDI plate This approach allowed detection commonly observed crocins C-1-C-6 flavonols, together identification unknown highly glycosylated C-7, C-8 C-9, carotenoid-derived...
The quality of extra virgin olive oil is associated with the presence microcomponents whose healing effects have been proved in some special cases. enzymatic hydrolysis oleuropein and ligstroside, their demethylated analogues, affords four different pentanedialdehydes, for one which, 2-(4-hydroxyphenyl)ethyl (3S,4E)-4-formyl-3-(2-oxoethyl)hex-4-enoate, also known as oleocanthal, an anti-inflammatory effect was quite recently carefully assessed. Extra now worldwide considered a functional...
