While several validated methods have been developed for analysis of phenylurea herbicides in staple food plants, analytical procedures suitable for their quantification in minor crops such as poppy seeds are not available. For the registration of isoproturon use in this crop, the documentation of dynamics of its residues following treatment was requested. To accomplish this task, HPLC-MS/MS method was developed. Extraction of residues was realised by methanol-water mixture, Supelclean LC-18 SPE cartridges were used for purification of crude extracts. For HPLC separation of isoproturon SPE fraction Lichrospher C18 column (25 cm × 4 mm, 5 μm) was employed. For detection and quantification of target analyte, mass spectrometer with ion trap analyser operated in positive atmospheric pressure chemical ionisation (APCI) and MS/MS mode was used. Following performance parameters of method were obtained: detection limit 0.01 mg/kg, recovery 84%, and repeatability 7%.

INTRODUCTION: Human breast cancer resistance protein (BCRP, ABCG2) is a transport protein of ABC superfamily of transporters that uses ATP energy of for its work. BCRP plays an important role in the pharmacokinetics of drugs, therefore all new drugs are recommended to be tested for belonging to its substrates, inducers and inhibitors. The influence of substances on the activity of this transport protein in vitro is evaluated by a change of transmembrane transfer of its substrates, one of which being quercetin. This, in turn, requires the development and validation of a method for its quantitative analysis in an appropriate matrix. AIM: To develop a method for the quantitative determination of quercetin using high performance liquid chromatography (HPLC) with tandem mass selective detection (MS/MS) with full validation. MATERIALS AND METHODS: The method was developed on Ultimate 3000 HPLC equipped with TSQ Fortis (Thermo Fisher, USA) MS/MS detector. The conditions of chromatographic analysis were as follows: column UCT Selectra C18 4.6 mm*100 mm 5μm, 100 A, Selectra C18 Guard Cartridges SLC-18 GDC46-5UM. The analysis time was 11 min at separation temperature 35°С, flow rate 0.5 ml/min, injected sample volume 5 μl. Gradient elution regime was used: on 0th minute, the ratio of 0.1% formic acid solution and acetonitrile was 70% and 30%; 0.3 min — 30% and 70%; 4 min — 1% and 99%; 9 min — 70% and 30%. Quercetin retention time was 3.91 minutes. Detection conditions: negative ionization mode, 301 m/z → 150.9 m/z with collision energy 22 V, 301 m/z →178.9 m/z with collision energy 17 V, source fragmentation 5 V, electrospray voltage 3 000 V, CID gas pressure 1 mTorr, Sheath gas 50 Arb, Aux gas 10 Arb, Sweep gas 10 Arb, ion transfer tube temperature 300°C, vaporizer temperature 350°C. The matrix was transport medium after incubation for 3 hours with Caco-2 cells overexpressing BCRP. In this medium, the transport of quercetin through the cell monolayer was further evaluated in vitro. Precipitation of protein and isolation of quercetin from the transport medium was realized by a mixture of water and acetonitrile in a ratio of 1:1. RESULTS: The developed method was validated by the following parameters: selectivity, linearity, accuracy, precision, limit of quantification, sample transfer, matrix effect, sample stability. The analytical range of the technique was 5–500 nmol/l. In this case, the correlation coefficient was more than 0.99. The limit of detection and the lower limit of quantification of quercetin (LLQQ) were 1 and 5 nmol/l, respectively. The calculation of intra- and inter-cycle accuracy and precision showed that these parameters do not exceed 20% for the concentration corresponding to the lower limit of quantitative determination, and 15% for other concentrations. The analyte demonstrated stability in triple freeze-defreeze cycle at -80°C, in storage at -80°C for 60 days, after sample preparation and being kept in the autosampler for 24 hours. There was no sample transfer and no matrix effect. CONCLUSION: A method for the quantitative determination of quercetin using HPLC-MS/MS in a transport medium was developed and fully validated.

Knowledge about selenium content of foods containing selenium species is very important in terms of both nutrition and toxicity. Bioavailability of selenium species for human body is different from each other. Hence, speciation of selenium is more important than total selenium determination. In the selenium speciation study, chicken breast samples, selenium supplement tablets and egg samples were analyzed for their selenium contents. In chicken breast study, chickens were randomly categorized into three groups including the control group (25 chickens), inorganic selenium fed group (25 chickens) and organic selenium fed group (25 chickens). After the optimization of all the analytical parameters used throughout the study, selenomethionine, selenocystine, Se(IV) and Se(VI) were determined using Cation Exchange-HPLC-ICP-MS system. In selenium supplement tablet study, anion and cation exchange chromatographies were used to determine selenium species. Arsenic is known as toxic element, and toxicity of inorganic arsenic species, As(III) and As(V), is much higher than organic arsenic species like arsenobetaine and arsenosugars. Hence, speciation of arsenic species in any matrix related with human health is very important. In the arsenic speciation study, Cation Exchange-HPLC-ICP-MS and Cation Exchange-HPLC-ES-MS systems were used to determine arsenobetaine content of DORM-2, DORM-3 and DOLT-4 as CRMs. All of the parameters in extraction, separation and detection steps were optimized. Standard addition method was applied to samples to eliminate or minimize the matrix interference. Thiols play an important role in metabolism and cellular homeostasis. Hence, determination of thiol compounds in biological matrices has been of interest by scientists. In the thiol study, Reverse Phase-HPLC-ICP-MS and Reverse Phase-HPLC-ES-MS systems were used for the separation and detection of thiols. For the thiol determination, thiols containing &ndash
S-S- bond were reduced using dithiothreitol (DTT). Reduction efficiencies for species of interest were found to be around 100%. Reduced and free thiols were derivatized before introduction on the column by p-hydroxymercuribenzoate (PHMB) and then separated from each other by using a C8 column. In the real sample measurement, yeast samples were analyzed using HPLC-ES-MS system.

Kehossa esiintyy luontaisesti useita anabolisia androgeenisia steroidiyhdisteitä, joista lihasmassan kasvun ja sen ylläpidon kannalta merkittävin on testosteroni. Testosteronin voimakkaan anabolisen vaikutuksen takia siitä on tehty useita muunnelma, joilla on pyritty minimoimaan androgeenista vaikutusta, maksimoimaan anabolista tehoa ja esimerkiksi vaikuttamaan yhdisteen vapautumiseen kehossa. Luontaisetja synteettiset anaboliset androgeenit ovat sekä rakenteeltaan että toiminnaltaan testosteronin kaltaisia. Anabolisten androgeenien ja muiden steroidiyhdisteiden aineenvaihdunta on monimutkaista, sisältäen useita entsyymiavusteisia reaktioita, minkä johdosta steroidiyhdisteiden analysointi voi olla haastavaa ja tiettyä yhdistettä voidaan tutkia suoraan tai useiden eri markkerien tai metaboliittien avulla. Steroidiyhdisteiden analytiikassa aineenvaihdunta huomioidaan näytteenkäsittelyssä. Virtsan sisältämät steroidit ovat suurilta osin glukuronidikonjugaatteja, joiden lisäksi virtsassa esiintyy sulfaattikonjugaatteja ja muita aineenvaihduntatuotteita. Näytteenkäsittelyssä glukuronidikonjugaatit yleensä hydrolysoidaan takaisin vapaaseen steroidimuotoon ja näytteet uutetaan poolittomien ja poolisten yhdisteiden erottamiseksi. Laitekomponenttien ja menetelmän kehittyminen on mahdollistanut myös suoraruiskutusmenetelmän soveltamisen. Steroideja voidaan analysoida virtsasta perinteisen kaasukromatografia-massaspektrometrin lisäksi mm. korkean erotuskyvyn nestekromatografialla kytkettynä tandem massaspektrometriin. Menetelmää voidaan käyttää sekä kvantitatiivisiin että kvalitatiivisiin analyyseihin ja sen etu on lämpöherkkien yhdisteiden analysointi, herkkyys ja automaation helppous. Steroidianalyyseissä nestekromatografisessa erotuksessa käytetään yleisimmin käänteisfaasierotusta ja gradienttimenetelmää. Ionisointi suoritetaan sähkösumutusionisaatiolla tai kemiallisella ionisaatiolla normaali ilmanpaineessa, sillä kyseiset ionisaatiomenetelmät aiheuttavat vähän fragmentaatiota. Massa-analysaattorina käytetään yleisimmin kolmoiskvadrupolia, mutta myös ioniloukku- ja lentoaika-analysaattoreita yhdistettynä kvadrupoliin. Korkean erotuskyvyn nestekromatografia kytkettynä tandem massaspektrometriin sisältää useita eri muuttujia, joita vaihtelemalla, säätämällä ja optimoimalla voidaan vaikuttaa analyysituloksiin. Menetelmän erilaisten mahdollisuuksien määrä mahdollistaa lukuisten erilaisten yhdisteiden analysoinnin ja menetelmän edelleen kehittymisen.

Il presente lavoro di tesi ha l’obiettivo di studiare dal punto di vista chimico, il tabacco “kentucky” coltivato e lavorato in alcune zone della Regione Veneto. Questo tipo di produzione agricola è considerata di nicchia e la caratterizzazione e quantificazione dei suoi principali costituenti chimici non è mai stata approfondita. Nel presente lavoro di tesi si sono individuati alcuni componenti chimici sviluppando e/o perfezionando metodi analitici utili all’individuazione di una "impronta digitale" chimica del tabacco Kentucky veneto. Il Kentucky è un tabacco scuro appartenente alla classe dei cosiddetti fire cured (cura a fuoco), cioè i tabacchi seccati attraverso il fumo di legni speciali che, penetrando lentamente nelle foglie, ne conferiscono un particolare aroma e il colore scuro. I metodi analitici sviluppati hanno reso possibile l’individuazione e la quantificazione di una serie di composti inorganici ed organici in foglie di tabacco kentucky dopo la cura a fuoco coltivato nel Veronese e in campioni di tabacco lavorato. Il lavoro svolto in laboratorio prevede due fasi lavorative. La prima, consiste nella quantificazione di analiti di tipo inorganico attraverso la digestione acida in microonde delle foglie di sigaro per poter analizzare in ICP-MS la quantità di metalli pesati presenti in essi (TE e REE), tenendo presente dei possibili effetti di frazionamento isotopico che incidono sui risultati finali di concentrazione. La seconda fase invece include la quantificazione di analiti di tipo organico, nello specifico dell’alcaloide Nicotina e delle nitrosammine specifiche del tabacco NNN e NNK (noti anche come, rispettivamente, N-nitrosornicotina e 4-(metilnitrosamino)-1-(3-piridil)-1-butanone) tramite estrazione con MeOH dei campioni già polverizzati e successive analisi. La quantificazione è avvenuta via GC-MS per la nicotina e via HPLC-MS/MS per quanto riguarda le nistrosammine. L'utilizzo di un materiale certificato di riferimento ha permesso di validare i metodi per la quantificazione degli analiti. I risultati ottenuti sono stati sottoposti ad una analisi statistica preliminare per valutare correlazioni utili a individuare una possibile indicazione di tracciabilità.

Lysophosphatidic acid (LPA) is a bioactive lipid with a plethora of biological functions, including roles in cell survival, proliferation, and migration. Although high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC ESI-MS/MS) technology has been used to measure the levels of LPA in human blood, serum and plasma, current methods cannot readily detect the minute levels of LPA from cell culture. In this study, a novel HPLC ESI-MS/MS method with enhanced sensitivity was developed which allows accurate measurements of LPA levels with a limit of quantitation at approximately 10 femtomoles. The method was validated by quantitation of LPA levels in the media of previously characterized cell lines ectopically expressing autotaxin. Autotaxin overexpression induced an increase in several subspecies of LPA while others remained unchanged. Lastly, this HPLC ESI-MS/MS method was validated via biological assays previously utilized to assay LPA production. Hence, this new HPLC ESI-MS/MS will allow researchers to measure in vitro LPA levels and also distinguish between specific LPA subspecies for the delineation of individual biological mechanisms.

There is an ever-increasing need to develop analytical methods for the detection of steroids, NSAIDs, fibrates, iothalamates and fatty acids for therapeutic, forensic, medical and pharmaceutical applications. Hence, the primary aim of the project was to develop new methods for detection of these classes of drugs in different human. body matrices using chromatographic techniques like enzyme-linked immunosorbent assay [ELISA], HPLC-UVIDADÆLSD, LC-MS/MS and GC-MS/MS. The new methods developed were capable of detecting the drugs: prednisolone, cortisol, prednisone, nandrolone, stanozolol, testosterone, diclofenac, fenofibric acid, iothalamic acid, monoolein, diolein, triolein, palmatic acid, stearic acid and linolenic acid. The methods were validated for LLOD, specificity, accuracy, precision, linearity and accuracy according to FDA and ICH guidelines in a cGLP-accredited lab. The assay was linear in the range 1 to 400 pg/mg for stanozolol, 0.5 to 400 pg/mg for testosterone and 3 to 400 pg/mg for nandrolone. The linear range for the routine assays were from 1 to 25 ng/mI with no interference from matrices. The calibration standards and quality controls were prepared in fresh human matrices. New internal standards were developed and added to all aliquots of samples. All methods showed good precision, accuracy, recovery and linearity. LLODs for non-steroidal anti inflammatory drugs were found to be in the range of 0.02 ng/ml to 10 ng/mI in plasma, urine and synovial fluid. Corticosteroids were analysed in the range of 5 ng/ml to 50 ng/mI. The anabolic steroids assays were capable of detecting 0.25 pg testosterone, 0.5 pg stanozolol and 2.5 pg nandrolone as a LLOD per mg of hair when approximately 20 mg of hair was processed. The assay was linear in the range 1 to 400 pg/mg for stanozolol, 0.5 to 400 pg/mg for testosterone and 3 to 400 pg/mg for nandrolone. lothalamates were found to be in the range of 0.25 ug/ml to 0.5 ug/ml, fibrates 5 to 25 ng/mI and diuretics in 1-5 ng/ml range. The extended lower limits of detection and lower limits of quantification would help in the detection of these drugs even at very low concentrations in matrices. Hair, urine, plasma, synovial fluids etc from subjects that were found positive for steroidal, non-steroidal drugs, corticosterides and others by ELISA screens were successfully quantified on HPLC, GC-MS and LC-MS/MS. In conclusion, the results obtained demonstrate the application of hair analysis to detect steroids in line with WADA requirements at lower concentrations. These novel methods have been developed and validated in human plasma, urine, synovial fluids, gastrodeudenal fluids and hair using improved extraction techniques. In addition, new solvents have been added to the samples as a deproteination agent, which increased the recovery of most drugs. Narrow bore column technology has been used to detect lower levels of drugs in matrices. These revised processes allowed clean extraction and near-quantitative recovery of analyte (>95%).

Resumo:
Harmful algal blooms (HABs) are occurring with increasing frequency and severity across the globe in part due to climate change and anthropogenic pollution (Bullerjahn et al. 2016). HABs produce several classes of toxins; however, microcystins (MCs) are the most commonly studied (Lone et al. 2015) and can be potent toxins with LD50s in the range of 50 μg/kg (Puddick et al. 2014). Sample analysis in laboratories, typically by high-pressure liquid chromatography tandem mass spectrometry (HPLC-MS/MS) or by Enzyme Linked Immunosorbent Assays (ELISAs) (USEPA 2015). These analytical techniques are highly sensitive and selective for the given toxins; however, the time it takes to collect, transfer, prepare, and analyze a sample before the data can be reported is significant; often, multiple days is the most expeditious.

Resumo:
No standard method exists for determining levels of insensitive munition (IM) compounds in environmental matrices. This project resulted in new methods of extraction, analytical separation and quantitation of 17 legacy and 7 IM compounds, daughter products of IM, and other munition compounds absent from USEPA Method 8330B. Extraction methods were developed for aqueous (direct-injection and solid-phase extraction [SPE]), soil, sediment, and tissue samples using laboratory-spiked samples. Aqueous methods were tested on 5 water sources, with 23 of 24 compounds recovered within DoD QSM Ver5.2 limits. New solvent extraction (SE) methods enabled recovery of all 24 compounds from 6 soils within QSM limits, and a majority of the 24 compounds were recovered at acceptable levels from 4 tissues types. A modified chromatographic treatment method removed analytical interferences from tissue extracts. Two orthogonal high-performance liquid chromatography-ultraviolet (HPLC-UV) separation methods, along with an HPLC–mass spectrometric (HPLC-MS) method, were developed. Implementing these new methods should reduce labor and supply costs by approximately 50%, requiring a single extraction and sample preparation, and 2 analyses rather than 4. These new methods will support environmental monitoring of IM and facilitate execution of risk-related studies to determine long-term effects of IM compounds.
