Statin-like principles of bergamot fruit (Citrus bergamia): isolation of 3-hydroxymethylglutaryl flavonoid glycosides.
TLDR
The 3-hydroxy-3-methylglutaryl neohesperidosides of hesperetin and naringenin were isolated and detected from the fruits of bergamot and the structures were determined by spectroscopic and chemical methods.
Design, Synthesis, and Evaluation of Donepezil-Like Compounds as AChE and BACE-1 Inhibitors.
TLDR
An ecofriendly synthetic pathway for the synthesis of donepezil precursors is described and two potential new lead compounds for a dual therapeutic strategy against Alzheimer's disease were envisaged.
Assay of the set of all Sudan azodye (I, II, III, IV, and Para-Red) contaminating agents by liquid chromatography-tandem mass spectrometry and isotope dilution methodology.
TLDR
A high-throughput mass spectrometric method is presented for the simultaneous detection of Sudan I, II, III, IV, and Para-Red azodyes in foodstuff using deuterium-labeled internal standards and atmospheric pressure chemical ionization in a triple-quadrupole instrument.
Secondary metabolism of olive secoiridoids. New microcomponents detected in drupes by electrospray ionization and high-resolution tandem mass spectrometry.
TLDR
The structures of a number of new microcomponents, detected and isolated by a combined high-performance liquid chromatography-fraction collector/ultraviolet electrospray ionization mass spectrometry (UV/ESI-MS) apparatus, can be inferred from the data obtained by high-resolution tandem mass Spectrometry in a QqTOF instrument.
Characterization of new phenolic compounds from leaves of Olea europaea L. by high-resolution tandem mass spectrometry.
TLDR
A set of minor constituents of Olea europaea L. leaves have been identified and characterized by electrospray ionization tandem mass spectrometry (ESI-MS/MS) and high-resolution measurements and could provide tools for a full understanding of the secondary metabolism of this plant in relation to the biosynthesis of the phenolic species.
High-throughput mass spectrometry: the mechanism of sudan azo dye fragmentation by ESI tandem mass spectrometry and extensive deuterium labeling experiments.
TLDR
The mechanism of the fragmentation of the azo double bond from the protonated precursor is discussed with reference to the behavior of deuterium-labeled reference compounds and the results can be used for the detection of potential carcinogenic compounds in different matrices by means of the isotope dilution method.
Tunable microwave-assisted method for the solvent-free and catalyst-free peracetylation of natural products
TLDR
A totally green, solvent-free and catalyst-free microwave (MW)-assisted method for peracetylation of natural products such as oleuropein, alpha-hederin, quercetin and rutin, potentially easily scalable for industrial applications, including pharmaceutical, cosmetic and food industry.
