Opis:
Tomato is an economically important vegetable crop which is attacked heavily by insect pests leading to reduction of yield and quality of the fruits. Field experiments were carried out to investigate the dissipation of methomyl (a common insecticide) used mainly on tomato fruits. LC-MS/MS coupled with the QuEChERS method were used for the determination of methomyl. The results showed that the recovery using matrix-matched standards ranged from 87.8 to 101.3%, with relative standard deviation of 2.5 to 7.5%. Kinetics equation, Log R = log R0 – 0.434 Kt, was used to calculate the rate of degradation in tomato, soil and water. Residue half-life calculated using kinetic rate ranged from 1.95 to 1.63 days in tomato and soil, respectively. From the results it was concluded that tomato fruits can be safely harvested for consumption after 15 days of application based on estimated preharvest interval (PHI). It is advisable to re-estimate the PHI regularly owing to data from the EU and Codex.

Opis:
The rapid analytical method was developed in response to increasing concern over the environmental impact of azoles (sterol biosynthesis inhibitors) and neonicotinoids (nicotinic acetylcholine receptor site). These chemicals are commonly used to protect fruit and vegetables crops against fungi and pests. Seven insecticides and twenty one fungicides commonly occurring in food industrial wastewater have been determined. For this purpose, active substances from two new pesticide classes were extracted and isolated by QuEChERS by addition of acetonitrile, buffering salts and chitin as a clean-up sorbent. The novelty of this procedure was one step sample preparation including extraction and removing of co-extracts in short time. Instrumental analysis was conducted by liquid chromatography coupled with mass spectrometry using multiple reaction monitoring. The limits of detection ranged from 0.002 to 0.005 μg·L-1 with satisfactory accuracy and precision The recoveries for the pesticides ranged from 81–103%, with high repeatability (n = 3, RSD ≤ 9%) and low LOQs (0.01 μg·L-1). Matrix effects calculated were less than 12% for all analyses. The method was applied to routine analysis of food industrial wastewater. Concerning the results, total pesticide levels in most cases were below 1 μg·L -1. The most significant pesticides in terms of concentration and frequency of detection were acetamiprid (0.07 μg· L-1); tebuconazole (1.2 μg· L-1) and thiacloprid (0.04 μg·L-1).

Opis:
Introduction and objective. Acrylamide is a “probably human carcinogen” monomer that can form in heated starchy food as a result of a reaction between asparagine and reducing sugars via Maillard reaction. The main source of acrylamide in human diet are potato products, cereal products and coffee. Tobacco smoke may be another significant source of exposure to acrylamide. The aim of our study was to determine acrylamide content in cigarettes available on the Polish market and to estimate the exposure to acrylamide originating from tobacco smoke in smokers in Poland. Materials and methods. The material was cigarettes of the top five brands bought in Poland and tobacco from non-smoked cigarettes. Acrylamide content in cigarettes mainstream smoke was determined by LC-MS/MS. Exposure assessment was carried out using analytical data of acrylamide content in cigarettes and the mean quantity of cigarettes smoked daily by smokers in Poland, assuming body weight at 70 kg. Results. The mean content of acrylamide was 679.3 ng/cigarette (range: 455.0 – 822.5 ng/cigarette). The content of acrylamide was evidenced to correlate positively with total particulate matter (TPM) content in cigarettes. The estimated average exposure to acrylamide from tobacco smoke in adult smokers in Poland is 0.17 μg/kg b.w./day. Conclusions. Our results demonstrate that tobacco smoke is a significant source of acrylamide and total exposure to acrylamide in the population of smokers, on average, is higher by more than 50% in comparison with non-smokers. Our estimation of exposure to acrylamide from tobacco smoke is the first estimation taking into account the actual determined acrylamide content in the cigarettes available on the market.

Opis:
A rapid, accurate and precise LC-MS method is described for the quantitative determination of pramipexole in human plasma matrix using ropinirole as internal standard. Pramipexole and ropinirole were extracted from plasma by liquid-liquid extraction technique. The method was validated over the concentration range of 100-2514 pg/mL. The method was found to have acceptable accuracy, precision, linearity and selectivity. The mean extraction recovery from spiked plasma samples was in the range of 79.415-87.00 %. The intra-day accuracy of the assay ranged from 98.924 to 112.236 % and intra-day precision ranged from 3.489 to 6.756 %. Inter-day accuracy and precision results for quality control samples ranged between 100.340 and 107.443% of nominal and precision is observed to be 3.970-5.714 %. The pramipexole was found to be stable after several stability studies. The proposed method yielded a quick, simple and reliable protocol for estimating pramipexole concentrations in human plasma.

Opis:
Background: Lopinavir, saquinavir, and ritonavir are viral protease inhibitors (PIs) developed for and widely used in the therapy of human immunodeficiency virus (HIV)-related disease. These compounds are also active in vitro against the pathogens causing tuberculosis, malaria and coronavirus infections. PIs have been regarded as a platform for the design of inhibitors targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-encoded proteases. This study aimed to develop a liquid chromatography/mass spectrometry (LC/MS) procedure for accurate simultaneous determination of concentrations of these three PIs in the plasma. Methods: Samples of human plasma were protein precipitated with 0.3 M zinc sulfate in a water/methanol solution (30:70, v/v). The extracts were analyzed with reversed-phase chromatography coupled with the electrospray ionization (ESI) source of the ion trap mass detector operating in mEass spectrometry (MS) and tandem mass spectrometry (MS/MS) modes. Results: Calibration curves demonstrated good linearity from 0.01 to 10 µg/mL and acceptable reproducibilities and recoveries. Conclusions: The described procedure proves that a very basic ion-trap LC/MS system could be applied for selective, rapid, and precise determination of antiviral protease inhibitors.

Opis:
Background Cytotoxic antineoplastic drugs (ADs), widely used in treating cancer, are considered hazardous in the workplace and thus require safe handling practices. An analytical protocol for environmental and biological AD monitoring in the healthcare environment has been developed, since Europe lacks clear guidelines and regulations for cytostatic preparation and handling. Material and Methods Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for measuring contemporaneously 20 multi-class cytostatic compounds and urinary α-fluoro-β-alanine, whereas platinum was detected by inductively coupled plasma mass spectrometry (ICP-MS). Sampling procedures and analytical conditions were optimized and the assays were validated. Environmental AD monitoring data, collected in 2009–2017, for a total of 3749 wipe tests and 57 720 determinations, was evaluated. Results The proportion of positive samples gradually decreased from 11.7% in 2010 to 1% in 2017, however, 2266 determinations were positive. No urine sample had detectable concentrations of any of the 4 drugs considered (0/398 samples). Conclusions These improvements are so large that the key role played by the new, more stringent rules for preparing and administering ADs is evident. Hence, the analytical method involving multi-element determinations allows for a more thorough and complete investigation into the AD contamination of work environments. Med Pr 2018;69(6):589–604

Opis:
Beta vulgaris L. is an important source of bioactive saponins – a group of secondary metabolites – that have spurred a growing interest due to their health-promoting properties. This study aimed to gain information on triterpene saponin profile of the peel and flesh of white, yellow and red beet of six cultivars – Snow Ball, Boldor, Ceryl, Chrobry, Forono and Tytus – harvested in Poland, in the same region. Twenty four saponins with oleanolic acid, hederagenin, akebonoic acid and gypsogenin as aglycons were identified and quantified by liquid chromatography/tandem mass spectrometry (LC-ESI-MS/MS). Among them, betavulgaroside I, II, III and IV were the major compounds, but the quantitative profile of saponins was found to be dependent on beet cultivar and root part, respectively. The highest content of saponins was found in the peel of yellow B. vulgaris Boldor (20812 mg/kg fresh weight, fw), while the lowest saponin content was determined in the flesh of white B. vulgaris Snow Ball (497 mg/kg fw). In addition, the total saponin content in peel and flesh in yellow beet (26054 mg/kg fw) was much higher than the total content in peel and flesh in red beet Tytus (8364 mg/kg fw) and white beet Snow Ball (1204 mg/kg fw). This is the first report on the profile of saponins in white and yellow beets.

This study was focused on the identification and quantification of betaxanthins using high-performance liquid chromatography with a diode array detector coupled to electrospray ionisation mass spectrometry (HPLC-DAD-ESI-MS) in leaves of various cultivars of Beta vulgaris (beet) and Gymnocalycium mihanovichii grafted cacti. In G. mihanovichii grafted cacti, four betaxanthins, namely histidine-Bx, histamine-Bx, serine-Bx, and proline-Bx, were tentatively identified in the yellow, orange, pink, and red varieties, with contents ranging from 0.09 to 1.55 mg/kg fresh weight (FW). Betaxanthins were not detected in the green cactus. Histidine-Bx was the prevailing betaxanthin compound in the majority of cultivars. Fifteen betaxanthins were successfully identified in the leaves of five B. vulgaris cultivars (cv.): Snow Ball, Boldor, Cylindra, Rhubarb, and Round Dark Red. Leaves of yellow beet (cv. Boldor) had the highest total betaxanthin content (20.4 mg/kg FW), while white beet (cv. Snow Ball) had the lowest one (3.43 mg/kg FW). The leaves of red cultivars had comparable betaxanthin contents, ranging from 13.4 to 18.8 mg/kg FW, similary to the yellow cultivar, indicating their potential as valuable sources of betaxanthins. There was no single dominant betaxanthin in B. vulgaris leaves. The leaves of B. vulgaris were found to be a richer source of betaxanthin than the grafted cactus G. mihanovichii, which opens up new prospects for research into the potential utilization of these compounds in the industry.

The study investigates the relationship between soilsthat vary for different basic physicochemical parameters (pH,phosphorus and potassium content, granulometric compositionand soil organic matter content) and the free amino acids content of Stellaria media. According to some research, plant aminoacid profile is a good indicator of the condition of the soils onwhich plants are grown. In this experiment, a rapid and sensitiveliquid chromatography coupled with tandem mass spectrometry(LC-MS/MS) method was used for the identification and quantification of nineteen proteinogenic amino acids in Stellaria mediasamples, which is a very common weed found worldwide. Significant linkage was found between the soil parameters and Stellariamedia amino acid content. Garden soil is the most favourable soilfor amino acid content. Glutamine, glutamic and aspartic acid arethe most abundant amino acids in Stellaria media grown on allthree tested soils.

Opis:
Betacyanins are conjugates of betalamic acid and glycosylated cyclo-DOPA which bring about the creation of a specific chromophoric system, the 1,7-dia- zaheptamethin chain. Betanin, a betacyanin pigment from red beet (Beta vulga- ris L.), as well as its decarboxylated derivatives were subjected to reduction with the use of NaBH4. The pigment structures contain a vinyl linker which is postu- lated to be protonated during reaction with NaBH4. In this study, 17-decarboxy- betanin and 2,17-bidecarboxy-betanin were obtained from betanin, which had been previously isolated from red beet root (Beta vulgaris L.). Purified pigments were tested in the presence of the reduction reagent while looking for the prod- ucts of the reaction identified by LC-MS.

Opis:
Apple processing into juice generates vast amounts of a by-product, namely fruit pomace, which poses a serious problem for the processing industry. At the same time, fruit pomace features a high health potential. The aim of the present study was to develop recipes of 8 variants of cookies with wheat flour substituted by apple pomace (0, 10, 30 and 50% of flour weight), sweetened with sucrose and erythritol. The cookies were analyzed for their nutritional value; antioxidant capacity (ABTS•+ scavenging activity and oxygen radical absorption capacity – ORAC); the ability to inhibit α-amylase, α-glucosidase and pancreatic lipase; and consumer acceptability. In total, 13 phenolic compounds were identified in the cookies with pomace. Cookies with 50% addition of apple pomace had an approximately 8-fold higher content of dietary fibre than traditional products (without the apple pomace) and simultaneously reduced energy value (by 32.6 and 40.5 kcal/100 g of cookies sweetened with sucrose and erythritol, respectively). The antioxidant capacity of cookies was 0.032–0.316 mmol TE/100 g in the ABTS assay and 1.153–2.070 mmol TE/100 g when ORAC was determined. The IC50 enabling α-amylase and α-glucosidase inhibition ranged from 138.1 to 221.8 mg/mL and from 976.4 to 1374.9 mg/mL, respectively. The anti-lipase activity of cookies with the addition of 50% apple pomace and erythritol was the highest (IC50 of 7.3 mg/mL). Both antioxidant capacity and antidiabetic potential increased significantly with the increasing proportion of pomace in cookies. Replacing sucrose with erythritol favorably influenced the consumer assessment. The study results show that the proposed products can be a perfect alternative to traditional sweet snack products, especially for consumers with diet-related diseases. The feasibility of using waste raw materials, which are a challenge to the food industry, has been proven as well.
