Development of a high-performance liquid chromatography method for simultaneous quantification of sixteen polyphenols and application to tomato. J Chromatogr A 2024; 1733:465254. [PMID: 39173503 DOI: 10.1016/j.chroma.2024.465254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 07/24/2024] [Accepted: 08/08/2024] [Indexed: 08/24/2024]
Abstract
The main purpose of the current work was to develop a new method to evaluate and quantify sixteen polyphenol compounds from tomato fruit using high-performance liquid chromatography (HPLC). The separation of 16 polyphenols from tomato fruit was achieved in < 60 min by using a Waters Symmetry C18 column (250 × 4.6 mm i. d, 5 µm particle sizes) with a gradient system of ultrapure water (1 % acetic acid) and 100 % methanol, a temperature of 30 °C, an injection volume of 10 μL and a flow rate of 1.1 mL/min, respectively. The analytical characteristics of evaluation method provide sufficient sensitivity for all tomato polyphenols compounds within normal range 0.1-20 μg·mL-1 (R2≥0.999) with 0.069-0.365 μg·mL-1 LOD, and 0.171-1.106 μg·mL-1 LOQ, with good system suitability (<2 % RSD of retention time, peak area, and tailing factor, 6,000-1,336,000 N, and >1.5 peak resolution), <10 % RSD of precision, stability, repeatability, and robustness, and 99.2 - 105.0 % of recovery. The applicability of this method was demonstrated by the determination of polyphenols in nine cultivars of tomatoes. The results showed that '184' possessed the highest content of total polyphenols (1249.53 μg·g-1 DW) followed by 'Disease resistance 184' (1064.93 μg·g-1 DW). The main polyphenol components were rutin, quercetin, gallic acid, chlorogenic acid, 2,5-dihydroxy benzoic acid, caffeic acid and benzoic acid in tomato fruits. In conclusion, this novel HPLC method is useful and acceptable to analyze polyphenols in tomato fruit.

Abstract
Cow's milk allergy caused by a hypersensitivity to milk proteins has increased over the last years. Hypoallergenic responses can be induced by altering the structure of such proteins with chemical modifiers; this paper is about the creation of edible matrices based on polyphenols from orange peel. Some compounds were able to significantly lower the IgE binding from β-lactoglobulin allergic serum in sensitized patients. Such effects could also be observed for casein allergic serum in patients sensitized to both proteins. A certain inter-individual variability is observed, although polyphenols do actually induce salient structural changes. This indicates that molecular modifications aimed at oral treatments against food allergy may or may not correlate with reduced allergenicity, and hence the necessity for serum monitoring through immunological assays. Overall, the results are promising enough to validate the polyphenol-fortified approach. In addition, this study highlights the upgrading of vegetable waste, consistent with a circular economy in food chemistry.

Abstract
Sulfated phenolic acids are widely occurring metabolites in plants, including fruits, vegetables and crops. The untargeted UHPLC-QTOF-MS metabolomics of more than 50 samples from plant, fungi and algae lead to the discovery of a small group of sulfated metabolites derived from phenolic acids. These compounds were detected in land plants for the first time. In this study, zosteric acid, 4-(sulfooxy)benzoic acid, 4-(sulfoooxy)phenylacetic acid, ferulic acid 4-sulfate and/or vanillic acid 4-sulfate were detected in a number of edible species/products, including oat (Avena sativa L.), wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), tomato (Solanum lycopersicum L.), carrot (Daucus carota subsp. Sativus Hoffm.), broccoli (Brassica oleracea var. Italica Plenck), celery (Apium graveolens L.), cabbage (Brassica oleracea convar. sabauda L.), banana tree (Musa tropicana L.), pineapple fruit (Ananas comosus L.), radish bulb (Raphanus sativus L.) and olive oil (Olea europaea L.). The structural identification of sulfated compounds was performed by comparing retention times and mass spectral data to those of synthesized standards. In addition to above-mentioned compounds, isoferulic acid 3-sulfate and caffeic acid 4-sulfate were putatively identified in celery bulb (Apium graveolens L.) and broccoli floret (Brassica oleracea var. Italica Plenck), respectively. While sulfated phenolic acids were quantified in concentrations ranging from 0.34 to 22.18 µg·g-1 DW, the corresponding non-sulfated acids were mostly undetected or present at lower concentrations. The subsequent analysis of oat symplast and apoplast showed that they are predominantly accumulated in the symplast (> 70%) where they are supposed to be biosynthesized by sulfotransferases.

Benefits and Pitfalls of HPLC Coupled to Diode-Array, Charged Aerosol, and Coulometric Detections: Effect of Detection on Screening of Bioactive Compounds in Apples. Molecules 2021; 26:molecules26113246.

Abstract
The new screening method for rapid evaluation of major phenolic compounds in apples has been developed. Suitability of coupling HPLC/UHPLC separation with the diode-array detection and universal charged aerosol detection with respect to the presence of interfering substances was tested. Characteristics of both detection techniques were compared and method linearity, limits of detection and quantitation, and selectivity of them determined. Student t-test based on slopes of calibration plots was applied for the detailed comparison. The diode-array detection provided the best results regarding sensitivity and selectivity of the developed method in terms of evaluation of phenolics profiles. The response of the charged aerosol detector was negatively affected by co-eluting substances during rapid-screening analyses. Coulometric detection was used for advanced characterization of extracts in terms of antioxidant content and strength to obtain more complex information concerning sample composition. This detection also allowed evaluation of unidentified compounds with antioxidant activity. HPLC/UHPLC separation using a combination of diode-array and coulometric detectors thus represented the best approach enabling quick, yet complex characterization of bioactive compounds in apples.

Abstract
The development of a simple HPLC-UV method towards the evaluation of Spanish paprika's phenolic profile and their discrimination based on the former is reported herein. The approach is based on C18 reversed-phase chromatography to generate characteristic fingerprints, in combination with linear discriminant analysis (LDA) to achieve their classification. To this aim, chromatographic conditions were optimized so as to achieve the separation of major phenolic compounds already identified in paprika. Paprika samples were subjected to a sample extraction stage by sonication and centrifugation; extracting procedure and conditions were optimized to maximize the generation of enough discriminant fingerprints. Finally, chromatograms were baseline corrected, compressed employing fast Fourier transform (FFT), and then analyzed by means of principal component analysis (PCA) and LDA to carry out the classification of paprika samples. Under the developed procedure, a total of 96 paprika samples were analyzed, achieving a classification rate of 100% for the test subset (n = 25).

Abstract
The separation of seven phenolic compounds including gallic acid, chlorogenic acid, epicatechin, quercitrin, rutin, phloridzin, and phloretin present in apple peel and pulp and differing in elution properties has been optimized using high-performance liquid chromatography with diode array detection. Several stationary phases were tested to achieve the efficient separation of phenolic compounds in fruit extracts and C18 was found to be the most efficient. Core-shell and fully porous C18 packings were assessed with respect to the complex composition of the fruit extracts. The developed high-performance liquid chromatography method comprised gradient elution in which mobile phase A was water at pH 2.8 adjusted with acetic acid and B was acetonitrile. The gradient shape was the following: 0 min 95% A/5% B, 2.5 min 85% A/15% B, 12 min 50% A/50% B, 15 min 95% A/5% B. The flow rate was 1 mL/min, injection volume 10 μL, and UV detection at 255, 280, 320, and 365 nm was applied. Our method was validated for both C18 core-shell and fully porous packings. The resolution 6.2-14.8, symmetry 0.99-1.34, peak capacity 18-60, peak area repeatability 0.45-1.00% relative standard deviation, calibration range 0.125-5 mg/mL (0.25-10 mg/mL for chlorogenic acid and rutin), correlation coefficients of calibration curve 0.9976-0.9997, and accuracy evaluated as recovery 95.56-107.54% were determined for the core-shell column.

Abstract
The effect of controlled deficit irrigation (CDI) on the accumulation of carotenoids, polyphenols and l-ascorbic acid was studied in conventional and high lycopene tomato cultivars. Plants were initially irrigated to cover 100%ETc and after the fruit set phase, the dose was reduced to 75% or 50% of ETc. CDI had no significant effect on the accumulation of carotenoids, while it increased the levels of the hydroxycinnamic acids chlorogenic and ferulic acids, the flavonoid rutin and l-ascorbic acid. Nevertheless, there were important interactions and this effect was highly dependent on the year and site of cultivation. Certain growing areas would be more favorable to supply high quality markets, and, fortunately, CDI would maximize polyphenol (100-75%ETc) and l-ascorbic acid (100-50%ETc) in these areas. A combination of the best genotype and growing area with CDI would offer high quality products, preserving a scarce resource: water.

Abstract
U.S. pecans and Chinese hickory nuts possess a wide array of phenolic constituents with potential health benefits including phenolic acids and proanthocyanidins. Only limited information is available, however, on their compositions. The present study optimized the separation performance and characterized the low-molecular-weight phenolic fractions of these nuts with C18 and pentafluorophenyl (PFP) fused-core LC columns by employing a kinetic approach. Although both types of reversed-phase columns demonstrated similar performance in general, the PFP column furnished greater plate numbers and superior peak shapes for the low-molecular-weight fractions as well as overall separations of ellagic acid derivatives. The high-molecular-weight fraction of pecans, analyzed by a 3-μm HILIC column, possessed more proanthocyanidins than the Chinese hickory nuts with dimers and trimers (31.4 and 18.34 mg/g crude extract, respectively) being present at the greatest levels. Chinese hickory nuts had lower proanthocyanidin content but possessed tetramers and pentamers at 4.46 and 4.01 mg/g crude extract, respectively.

Abstract
The accumulation of polyphenols and l-ascorbic acid was evaluated under conventional (integrated pest management, IPM) and organic farming, as means to increase the accumulation of chemoprotective compounds. The effect of genotype was considerably higher than the growing system, in fact it is determining. 'Kalvert', a high-lycopene cultivar, outstood for the accumulation of most polyphenols, though low-carotenoid cultivars with high accumulation were also detected. Organic farming significantly increased the levels of caffeic acid by 20%, but reduced those of ferulic acid and naringenin by 13% and 15% respectively. A strong interaction with the environment was detected: in Navarra the differences were limited, while in Extremadura lower contents of ferulic acid and higher contents of chlorogenic acid and rutin were found in organic farming for certain cultivars. The effect of organic farming on l-ascorbic acid was dependent on cultivar and environment and it only led to an increase in Extremadura by 58%.

Optimization and validation of a rapid liquid chromatography method for determination of the main polyphenolic compounds in table olives and in olive paste. Food Chem 2017; 233:164-173. [PMID: 28530562 DOI: 10.1016/j.foodchem.2017.04.052] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2016] [Revised: 02/09/2017] [Accepted: 04/10/2017] [Indexed: 11/23/2022]
Abstract
A high performance liquid chromatography method, coupled to diode-array and fluorescence detectors, with a previous solid-liquid extraction, has been developed for the simultaneous detection and quantification of polyphenolic compounds in table olives and in olive paste. The effects of extraction variables have been studied by response surface methodology. The best conditions were extraction with 100% methanol (2mM NaF) during 30min for table olives, and 91% methanol (2mM NaF) during 40min for olive paste. Chromatographic separation of 26 polyphenols from different families was optimized. This method provides high linearity, in all cases higher than 98.65%, and high sensitivity whose detection limits ranged between 0.08 and 1.11μg/mL. The validated method has been applied for the determination of polyphenols in table olive and olive paste samples. The intra-day and inter-day assay repeatability, in the analysis of real samples was less than 7.6 and 11%, respectively.

Improved method for the extraction and chromatographic analysis on a fused-core column of ellagitannins found in oak-aged wine. Food Chem 2017; 226:23-31. [PMID: 28254015 DOI: 10.1016/j.foodchem.2017.01.043] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2016] [Revised: 01/05/2017] [Accepted: 01/10/2017] [Indexed: 11/30/2022]
Abstract
A new method for the analysis of ellagitannins observed in oak-aged wine is proposed, exhibiting interesting advantages with regard to previously reported analytical methods. The necessary extraction of ellagitannins from wine was simplified to a single step of solid phase extraction (SPE) using size exclusion chromatography with Sephadex LH-20 without the need for any previous SPE of phenolic compounds using reversed-phase materials. The quantitative recovery of wine ellagitannins requires a combined elution with methanol and ethyl acetate, especially for increasing the recovery of the less polar acutissimins. The chromatographic method was performed using a fused-core C18 column, thereby avoiding the coelution of main ellagitannins, such as vescalagin and roburin E. However, the very polar ellagitannins, namely, the roburins A, B and C, still partially coeluted, and their quantification was assisted by the MS detector. This methodology also enabled the analysis of free gallic and ellagic acids in the same chromatographic run.

Abstract
A diet rich in vegetables has been associated with a reduced risk of many diseases related to aging and modern lifestyle. Over the past several decades, many researches have pointed out the direct relation between the intake of bioactive compounds present in tomato and a reduced risk of suffering different types of cancer. These bioactive constituents comprise phytochemicals such as carotenoids and polyphenols. The direct intake of these chemoprotective molecules seems to show higher efficiencies when they are ingested in its natural biological matrix than when they are ingested isolated or in dietary supplements. Consequently, there is a growing trend for improvement of the contents of these bioactive compounds in foods. The control of growing environment and processing conditions can ensure the maximum potential accumulation or moderate the loss of bioactive compounds, but the best results are obtained developing new varieties via plant breeding. The modification of single steps of metabolic pathways or their regulation via conventional breeding or genetic engineering has offered excellent results in crops such as tomato. In this review, we analyse the potential of tomato as source of the bioactive constituents with cancer-preventive properties and the result of modern breeding programs as a strategy to increase the levels of these compounds in the diet.

Development of an analytical method for the determination of polyphenolic compounds in vegetable origin samples by liquid chromatography and pulsed amperometric detection at a glassy carbon electrode. J Chromatogr A 2015; 1420:66-73. [PMID: 26456515 DOI: 10.1016/j.chroma.2015.09.082] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2015] [Revised: 09/23/2015] [Accepted: 09/28/2015] [Indexed: 01/17/2023]
Abstract
A sensitive and accurate method for the determination of polyphenolic compounds in artichoke bract extracts and olive mill wastewaters by liquid chromatography coupled with pulsed amperometric detection at a glassy carbon working electrode was developed. Preliminary experiments were carried out by cyclic voltammetry to investigate the electrochemical behavior of polyphenols under different mobile phase compositions, and to test the detection and cleaning electrode potentials. Chromatographic separations were performed by using a core-shell C18 column, eluted with acetic acid and acetonitrile, by combined concave-linear binary gradients. Under the optimized experimental conditions, a good column efficiency and peak symmetry were observed, also for stereo and positional isomeric compounds. The developed three-step potential waveform for pulsed amperometric detection was successfully applied for the sensitive chromatographic determination of polyphenols in artichoke extracts and olive mill wastewaters. Linearity, precision and sensitivity of the proposed method have been evaluated. A wide linear range of response (up to 20 mg/L) has been obtained for all the investigated compounds. Detection and quantification limits in the vegetable origin sample extracts were in the range 0.004-0.6 mg/L and 0.01-2mg/L, respectively, while the injection-to-injection repeatability (n=6) ranged from 5 to 13%. The obtained results confirmed the excellent sensitivity of the electrochemical detection, and its suitability for the determination of electroactive polyphenolic compounds at low concentration levels.
