The paper describes the development of a targeted quantitative method for the analysis of policosanols in hemp inflorescence. Policosanols are long chain aliphatic alcohols, with carbon chains typically in the range 20–36, with interesting biological activities. These compounds are typically separated by gas chromatography and only a few methods employ liquid chromatography for policosanols. In both cases, methods always include the derivatization of policosanols. In this study, policosanols were separated by ultra-high performance liquid chromatography without any derivatization and detected using high resolution mass spectrometry by formation of lithiated adducts. The procedure was optimized and a quantitative method was validated for the most abundant policosanols (with C24, C26, C27, C28, and C30 chain lengths) in industrial hemp inflorescence extracts. The method was used for the quantitative analysis of policosanols in five hemp types. Hemp wax was found rich in these compounds, especially C26 and C28 policosanols, which may prove useful for revalorization of wax by-products. Finally, the acquired data were also used to expand the search to the untargeted qualitative analysis of policosanols using Compound Discoverer. The untargeted method allowed the annotation of underivatized policosanols up to C33.

Chlorella vulgaris is a popular microalga used for biofuel production; nevertheless, it possesses a strong cell wall that hinders the extraction of molecules, especially lipids within the cell wall. For tackling this issue, we developed an efficient and cost-effective method for optimal lipid extraction. Microlaga cell disruption by acid hydrolysis was investigated comparing different temperatures and reaction times; after hydrolysis, lipids were extracted with n-hexane. The best recoveries were obtained at 140°C for 90 min. The microalgae were then analyzed by an untargeted approach based on liquid chromatography with high-resolution mass spectrometry, providing the tentative identification of 28 fatty acids. First, a relative quantification on the untargeted data was performed using peak area as a surrogate of analyte abundance. Then, a targeted quantitative method was validated for the tentatively identified fatty acids, in terms of recovery (78-100%), intra- and interday relative standard deviations (<10 and 0.98). The most abundant fatty acids were palmitic, palmitoleic, oleic, linoleic, linolenic, and stearic acids.

Soybeans (Glycine max) are an excellent source of dietary proteins and peptides with potential biological activities, such as antihypertensive, anti-cholesterol, and antioxidant activity; moreover, they could prevent cancer. Also, soy contains all the essential amino acids for nutrition; therefore, it represents an alternative to animal proteins. The goal of this paper was the comprehensive characterization of medium-sized and short peptides (two to four amino acids) obtained from simulated gastrointestinal digestion. Two different analytical approaches were employed for peptide characterization, namely a common peptidomic analysis for medium-sized peptides and a suspect screening analysis for short peptides, employing an inclusion list of exact m/z values of all possible amino acid combinations. Moreover, fractionation by preparative reversed-phase liquid chromatography was employed to simplify the starting protein hydrolysate. Six fractions were collected and tested for antioxidative activity by an innovative antioxidant assay on human gastric adenocarcinoma AGS cell lines. The two most active fractions (2 and 3) were then characterized by a peptidomic approach and database search, as well as by a suspect screening approach, in order to identify potential antioxidant amino acid sequences. Some of the peptides identified in these two fractions have been already reported in the literature for their antioxidant activity.

Wild neotropical blueberries, endemic of Central and South American areas, are promising yet still undisclosed sources of bioactive compounds. Most research studies have addressed wild and cultivated blueberries from Europe and North America, despite the extremely wide variety of wild neotropical species. In the present paper, for the first time, the phenolic composition of Disterigma alaternoides was investigated through ultra-high-performance liquid chromatography coupled to high-resolution mass-spectrometric analysis followed by accurate data analysis and compound validation with a dedicated structure-based workflow. D. alaternoides, which belongs to a closely related genus to that of the common blueberry, grows exclusively in the Andean regions over 2000 above sea level. Thanks to the dedicated analytical platform, 249 phenolic compounds were tentatively identified, including several anthocyanins, flavonoids, phenolic acids, and proanthocyanidins. Thenature and heterogeneity of identified phenolic compounds demonstrate once more the need for a more profound knowledge of such still uncharted matrices.

Cannabis sativa is traditionally classified according to five chemotypes based on the concentration of the main phytocannabinoids tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabigerol (CBG). However, cannabis chemovars and varieties very often present similar concentrations of such phytocannabinoids but different chemical profiles, which is unavoidably translated into different pharmacological effects when used for therapeutic purposes. For this reason, a more refined approach is needed for chemovar distinction, which is described in this study and named phytocannabinomics. The classification was achieved by a comprehensive characterization of the phytocannabinoid composition, by liquid chromatography coupled to high-resolution mass spectrometry untargeted metabolomics for the detection of over a hundred phytocannabinoids, and data analysis by chemometrics for chemovars differentiation. The method was developed on fifty cannabis varieties, grown under the same conditions, and was validated to discriminate between the standard chemotypes by partial least squares discriminant analysis. Then, the method was extended to consider the entire chemical variety of the cannabis accessions, by an unsupervised approach based on the principal component analysis. The latter approach clearly indicated several new subgroups within the traditional classifications, which arise from a unique composition of the minor phytocannabinoids. The existence of these subgroups, which were never described before, is of critical importance for evaluating the pharmacological effects of cannabis chemovars.

Prostate cancer, a leading cause of cancer-related deaths worldwide, principally occurs in over 50-year-old men. Nowadays there is urgency to discover biomarkers alternative to prostate-specific antigen, as it cannot discriminate patients with benign prostatic hyperplasia from clinically significant forms of prostatic cancer. In the present paper, 32 benign prostatic hyperplasia and 41 prostatic cancer urine samples were collected and analyzed. Polar and positively charged metabolites were therein investigated using an analytical platform comprising an up to 40-fold analyte enrichment step by graphitized carbon black solid-phase extraction, HILIC separation, and untargeted high-resolution mass spectrometry analysis. These classes of compounds are often neglected in common metabolomics experiments even though previous studies reported their significance in cancer biomarker discovery. The complex metabolomics big datasets, generated by the UHPLC-HRMS, were analyzed with the ROIMCR procedure, based on the selection of the MS regions of interest data and their analysis by the Multivariate Curve-Resolution Alternating Least Squares chemometrics method. This approach allowed the resolution and tentative identification of the metabolites differentially expressed by the two data sets. Among these, amino acids and carnitine derivatives were tentatively identified highlighting the importance of the proposed methodology for cancer biomarker research.

Industrial hemp (Cannabis sativa L.) represents an important plant, used for a variety of uses including pharmaceutical and nutraceutical purposes. As such, a detailed characterization of the composition of this plant could help future research to further exploit the beneficial effects of hemp compounds on the human health. Among the many compounds of hemp, fatty acids represent an interesting class of minor components, which has been overlooked so far. In this work, an untargeted approach based on liquid-chromatography coupled to a high-resolution mass spectrometry and a dedicated structure-based workflow for raw data interpretation was employed for the characterization of fatty acids from hemp inflorescences. A simple method, without any chemical derivatization, was developed for extraction and characterization of fatty acids leading to the tentative identification of 39 fatty acid species in the five hemp samples. A quantitative analysis on the untargeted data was initially performed, using peak areas as surrogate of analyte abundance for relative quantitation. Five fatty acids resulted the most abundant in all hemp samples, with ca. 90% of the total peak area. For these compounds a targeted quantitative method was validated, indicating that the most abundant ones were linolenic acid (1.39–7.95 mg g-1) and linoleic acid (1.04–7.87 mg g-1), followed by palmitic acid (3.74–6.08 mg g-1), oleic acid (0.91–4.73 mg g-1) and stearic acid (0.64–2.25 mg g-1).

Polyhydroxyalkanoates (PHAs) are well-known biodegradable plastics produced by various bacterial strains, whose major drawback is constituted by the high cost of their synthesis. Producing PHAs from mixed microbial cultures and employing organic wastes as a carbon source allows us to both reduce cost and valorize available renewable resources, such as food waste and sewage sludge. However, different types of pollutants, originally contained in organic matrices, could persist into the final product, thus compromising their safety. In this work, the exploitation of municipal wastes for PHA production is evaluated from the environmental and health safety aspect by determining the presence of polycyclic aromatic hydrocarbons (PAHs) in both commercial and waste-based PHA samples. Quantification of PAHs by gas chromatography-mass spectrometry on 24 PHA samples obtained in different conditions showed very low contamination levels, in the range of ppb to a few ppm. Moreover, the contaminant content seems to be dependent on the type of PHA stabilization and extraction, but independent from the type of feedstock. Commercial PHA derived from crops, selected for comparison, showed PAH content comparable to that detected in PHAs derived from organic fraction of municipal solid waste. Although there is no specific regulation on PAH maximum levels in PHAs, detected concentrations were consistently lower than threshold limit values set by regulation and guidelines for similar materials and/or applications. This suggests that the use of organic waste as substrate for PHA production is safe for both the human health and the environment.

Metaproteomic analysis of aquifer systems provides valuable information on the microbial populations, their influence on drinking water quality, and the effect on human health. In the present paper, an extraction and enrichment method by C18 extra‐wide pore cartridge was developed, optimized, and applied for the first time to the metaproteomic characterization of dissolved organic matter in groundwater samples. In particular, three elution procedures were tested and compared on water spiked with a yeast protein extract to maximize the recovery of proteins from a complex matrix. The maximum protein recovery was obtained by the use of two sequential elution buffers, one employing a denaturing agent and the other one containing an acidified organic solvent. A comprehensive metaproteomic analysis of the dissolved organic matter of groundwater was then performed by nanoHPLC coupled to high‐resolution mass spectrometry. A total of 239 proteins was identified; in agreement with the current knowledge on proteins in aquifer systems, most identified sequences derived from bacteria, protobacteria, and ciliates. The paper is the first metaproteomic study applied to groundwater samples with particular emphasis on the need for sample pretreatment to obtain comprehensive information on the proteome in dissolved organic matter.

Native peptides from sea bass muscle were analyzed by two different approaches: medium-sized peptides by peptidomics analysis, whereas short peptides by suspect screening analysis employing an inclusion list of exact m/z values of all possible amino acid combinations (from 2 up to 4). The method was also extended to common post-translational modifications potentially interesting in food analysis, as well as non-proteolytic aminoacyl derivatives, which are well-known taste-active building blocks in pseudo-peptides. The medium-sized peptides were identified by de novo and combination of de novo and spectra matching to a protein sequence database, with up to 4077 peptides (2725 modified) identified by database search and 2665 peptides (223 modified) identified by de novo only; 102 short peptide sequences were identified (with 12 modified ones), and most of them had multiple reported bioactivities. The method can be extended to any peptide mixture, either endogenous or by protein hydrolysis, from other food matrices.

The review describes the state of the art of phenolic characterization in food by liquid chromatography and mass spectrometry. From conventional targeted analysis, a special attention was devoted to metabolomics-based strategies, which are becoming increasingly popular in the characterization of phenolic compounds. Most works in the field exploit the profiling approach by annotation of full scan high resolution mass spectrometric data. To improve the confidence, the use of tandem and multistage mass spectrometry is emerging as a valuable strategy which can provide more insight in the structure and help differentiating the many isomeric compounds which are typical of this class. The efficiency, however, is strictly connected with data handling and bioinformatics to search databases and match product ion spectra. The different approaches, from profiling, through suspect screening to untargeted analysis, are described with a discussion on the limitations of each approach and future developments needed to improve identification confidence.

Due to the rapidly increasing resistance to conventional antibiotics, antimicrobial peptides are emerging as promising novel drug candidates. In this study, peptide fragments were obtained from yellowfin tuna muscle by simulated gastrointestinal digestion, and their antimicrobial activity towards Gram-positive and Gram-negative bacteria was investigated. In particular, the antimicrobial activity of both medium- and short-sized peptides was investigated by using two dedicated approaches. Medium-sized peptides were purified by solid phase extraction on C18, while short peptides were purified thanks to a graphitized carbon black sorbent. For medium-sized peptide characterization, a peptidomic strategy based on shotgun proteomics analysis was employed, and identification was achieved by matching protein sequence database by homology, as yellowfin tuna is a non-model organism, leading to the identification of 403 peptides. As for short peptide sequences, an untargeted suspect screening approach was carried out by means of an inclusion list presenting the exact mass to charge ratios (m/z) values for all di-, tri- and tetrapeptides. In total, 572 short sequences were identified thanks to a customized workflow dedicated to short peptide analysis implemented on Compound Discoverer software.

Phytocannabinoids are a broad class of compounds uniquely synthesized by the various strains of Cannabis sativa. Up to date, most investigation on phytocannabinoids have been addressed to the most abundant species, Δ9-tetrahydrocannabinol and cannabidiol, for their well-known wide range of pharmaceutical activities. However, in the recent years a large number of minor constituents have been reported, whose role in cannabis pharmacological effects is of current scientific interest. With the purpose of gaining knowledge on major and minor species and furnishing a strategy for their untargeted analysis, in this study we present an innovative approach for comprehensively identifying phytocannabinoids based on high-resolution mass spectrometry in negative ion mode, which allows discrimination of the various isomeric species. For a faster and more reliable manual validation of the tandem mass spectra of known and still unknown species, an extensive database of phytocannabinoid derivatives was compiled and implemented on Compound Discoverer software for the setup of a dedicated data analysis tool. The method was applied to extracts of the Italian FM-2 medicinal cannabis, resulting in the identification of 121 phytocannabinoids, which is the highest number ever reported in a single analysis. Among those, many known and still unknown unconventional phytocannabinoids have been tentatively identified, another piece in the puzzle of unravelling the many uncharted applications of this matrix.

Short peptides are of extreme interest in clinical and food research fields, nevertheless they still represent a crucial analytical issue. The main aim of this paper was the development of an analytical platform for a considerable advancement in short peptides identification. For the first time, short sequences presenting both natural and post-translationally modified amino acids were comprehensively studied thanks to the generation of specific databases. Short peptide databases had a dual purpose. First, they were employed as inclusion lists for a suspect screening mass-spectrometric analysis, overcoming the limits of data dependent acquisition mode and allowing the fragmentation of such low-abundance substances. Moreover, the databases were implemented in Compound Discoverer 3.0, a software dedicated to the analysis of short molecules, for the creation of a data processing workflow specifically dedicated to short peptide tentative identification. For this purpose, a detailed study of short peptide fragmentation pathways was carried out for the first time. The proposed method was applied to the study of short peptide sequences in enriched urine samples and led to the tentative identification more than 200 short natural and modified short peptides, the highest number ever reported.

Chestnut seeds are used for fresh consumption and for the industrial preparation of derivatives, such as chestnut flour. During industrial processing, large amounts of by-products are generally produced, such as leaves, flowers, shells and burs. In the present study, chestnut shells were extracted by boiling water in order to obtain polyphenol-rich extracts. Moreover, for the removal or non-phenolic compounds, a separation by preparative reverse phase chromatography in ten fractions was carried out. The richest fractions in terms of phenolic content were characterized by means of untargeted high-resolution mass spectrometric analysis together with a dedicated and customized data processing workflow. A total of 243 flavonoids, phenolic acids, proanthocyanidins and ellagitannins were tentatively identified in the five richest fractions. Due its high phenolic content (450.03 µg GAE per mg of fraction), one tumor cell line (DU 145) and one normal prostate epithelial cell line (PNT2) were exposed to increasing concentration of fraction 3 dry extract for 24, 48 and 72 h. Moreover, for DU 145 cell lines, increase of apoptotic cells and perturbation of cell cycle was demonstrated for the same extract. Those outcomes suggest that chestnut industrial by-products could be potentially employed as a source of bioresources.

Protein tyrosine O-sulfation is an important post-translational modification, as it has been correlated to inflammation, virus infection, and signal pathways. Nevertheless, methods for the characterization of protein sulfation by sulfopeptide enrichment are currently limited. In this Article, two standard compounds, representative of mono- and disulfated peptides, were used to compare the enrichment capabilities of five sorbent materials: two commercial weak anion-exchange mixed-mode sorbents (Strata X-AW and Oasis WAX) and three phosphopeptide enrichment materials based on affinity chromatography to either immobilized metals (IMAC) or metal oxides, i.e., Fe3+, TiO2, or Ti4+. The sulfopeptides were analyzed by ultrahigh-performance liquid chromatography (UHPLC) multiple-reaction monitoring analysis and were stable under all the tested experimental conditions. Recoveries of the enrichment step from spiked bovine serum albumin digests were >80% for the commercial Fe-IMAC kit and the Strata X-AW sorbent. Shotgun proteomics was used on the same samples to evaluate the selectivity, calculated as the number of coenriched peptides, and it was found to be better for the Fe-IMAC kit. Therefore, the Fe-IMAC protocol was embedded in a shotgun-proteomics workflow and applied to serum spiked with the sulfopeptides before protein dephosphorylation and digestion. The recovery of the entire analytical workflow was 20%, which was compatible with previous data on TiO2 phosphopeptide enrichment. Despite the potential, no sulfopeptide was confidently identified in serum digests by conventional shotgun proteomics, probably due to very low abundance of native sulfoproteins, poor ionization efficiency of sulfopeptides in the positive mode, and lack of unambiguous sulfopeptide identification by bioinformatics software. In this context, the use of negative-ionization mode with high-resolution mass spectrometry appeared promising to improve the sensibility and allow sulfopeptide identification in complex samples.

The determination of phospholipids in olive oil is challenging due to their low concentration. For this reason, a comparison of two solid phase extraction procedures, namely weak anionic exchange (WAX) and graphitized carbon black (GCB), is presented for the enrichment of phospholipids. Analyses were performed by liquid chromatography-high resolution mass spectrometry (LC-HRMS) and lipids were identified by Lipostar software. Compared to the WAX solid phase extraction, GCB demonstrated the best performance and provided 82 identified phospholipids vs only 32. The final method was validated for some representative phospholipids, showing good repeatability and recovery (63–101%). High sensitivity was reached, with detection limits in the range 9–36 ng g−1, never reported before for phospholipids in olive oil. A semi-quantitative analysis indicated phosphatidic acids and phosphatidylglycerols as the most abundant species, both in number and concentrations. The GCB-LC-HRMS-Lipostar platform can be successfully applied for a comprehensive polar lipidomic characterization of olive oils.

Recycling and recovering valuable resources from wastewater treatment plants is an important aspect in circular economy. The safe use of sludge and sludge-related products deriving from wastewater treatment strictly depends on their chemical contamination, especially by emerging pollutants. In this work, an analytical method was developed for the determination of a range of selected compounds, included in a recent European watch-list (macrolides, fluoroquinolones, neonicotinoids, carbamates and estrogens), in recovery materials from innovative pilot systems. Both the instrumental analysis by high-performance liquid chromatography-tandem mass spectrometry and the pre-treatment strategy (quick, easy, cheap, effective, rugged and safe technique) were optimized for the purpose. The final method performance were evaluated, revealing determination coefficients (R2) of 0.993–0.9999 for the matrix-matched calibration curves, good accuracy (recovery 68–104% and matrix effect 70–123%), satisfactory precision (relative standard deviation <20%) and limits of detection and quantitation in the low ng g−1 levels. Ten different recovery material samples were analyzed, showing contamination by few analytes, mainly antibiotics and estrone; ciprofloxacin and azithromycin were the most abundant compounds (up to 500–600 ng g−1). On the contrary, neonicotinoid pesticides were not detected, except for one sample (sample 10, the only compost material). The application of the described method is an essential part of a broader investigation on the suitability and safety of innovative materials coming from waste water treatment plants, in the view of a risk assessment related to their usage.

Protein and peptide phosphorylation regulate numerous pathological processes, however, their characterization is challenging due to their low abundance and transient nature. Therefore, nanomaterials are being developed to address this demanding task. In particular, carbon nanostructures are attracting interest as scaffolds for functional nanocomposites, yet only isolated studies exist on the topic, and little is known on the effect of nanocarbon morphology on templating nanocomposites. In this work, we compared oxidized carbon nanotubes, graphene oxide, oxidized carbon nanohorns and oxidized graphitized carbon black, as scaffolds for magnetized nanocomposites. The nanomaterials were extensively characterized with experimental and in silico techniques. Next, they were applied to phosphopeptide enrichment from cancer cell lysates for NanoHPLC-MS/MS, with selectivity as high as nearly 90% and several-thousand identification hits. Overall, new insights emerged for the understanding and the design of nanocomposites for phosphoproteomics.
