Simultaneous Analysis of Metabolite Residues from Degradation of Dithiocarbamates in Cereals Using Liquid Chromatography Coupled with Tandem Mass Spectrometry
Background and Objectives: Dithiocarbamates are groups of fungicides used to control pests of agricultural products. Analysis of these pesticides with liquid and gas chromatography instruments is associated with various problems due to the presence of metal groups in the structure of these compounds. Therefore, one of the ways for analysis the pesticides is to check the level of decomposition...
متن کاملDetermination of Mebudipine in Human Plasma by Liquid Chromatography–tandem Mass Spectrometry
In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...
متن کاملStructural analysis of saponins from medicinal herbs using electrospray ionization tandem mass spectrometry.
The underivatized saponins from Tribulus terrestris and Panax ginseng have been investigated by electrospray ionization multi-stage tandem mass spectrometry (ESI-MS(n)). In ESI-MS spectra, a predominant [M + Na](+) ion in positive mode and [M - H](-) ion in negative mode were observed for molecular mass information. Multi-stage tandem mass spectrometry of the molecular ions was used for detaile...

متن کاملProteome analysis of Cryptosporidium parvum and C. hominis using two-dimentional electrophoresis, image analysis and tandem mass spectrometry
Until recently, Cryptosporidium was thought to be a single species genus. Molecular studies now showthat there are at least 10 valid species of this parasite. Among them, two morphologically identical species, C.hominis and C. parvum are the most pathogenic identified to date and share 97% of identical genomes.Post-genomic analyses is therefore necessary to explore further the...
