“…Bu yöntemler arasında yer alan SPE ile daha hızlı, seçici, düşük maliyetle ayırma ve zenginleştirme yapılabilmekte ayrıca otomasyona uygun olan bu yöntem ile yüksek geri kazanım ve zenginleştirme faktörleri elde edilebilmektedir. Ayrıca organik çözücü sarfiyatının en az düzeyde tutulması ve birçok farklı teknikle beraber kullanımına olanak sağlaması yöntemin diğer avantajları arasında sayılabilir (22). SPE de kullanılan katı faz adsorban materyali seçimi çeşitlilik göstermekle beraber sentetik reçine ve türevleri, karbon, bakteri ve alg gibi biyolojik substratların kullanıldığı bilinmektedir (21).…”

“…Liquid extraction suffers from problems such as large sample and organic solvent consumption, complicated operation, low selectivity and low enrichment efficiency. Solid‐phase extraction (SPE) can decrease the consumption of organic solvent and simplify the extraction procedures to some degree, but the selectivity and enrichment efficiency are still limited by traditional SPE (Ouyang et al ., ; Wan Ibrahim et al ., ; Zhang et al ., , ). Selective extraction techniques are desirable to remove matrices and coexisting components, as well as enriching certain kinds of target molecules.…”

Hordenine is an active compound found in several foods, herbs and beer. In this work, a novel sorbent was fabricated for selective solid-phase extraction (SPE) of hordenine in biological samples. The organic polymer sorbent was synthesized in one step in the plastic barrel of a syringe by a pre-polymerization solution consisting of methacrylic acid (MAA), 4-vinylphenylboronic acid (VB) and ethylene glycol dimethacrylate (EGDMA). The conditions for preparation were optimized to generate a poly(MAA-VB-EGMDA) monolith with good permeability. The monolith exhibited good enrichment efficiency towards hordenine. By using tyramine as the internal standard, a poly(MAA-VB-EGMDA)-based SPE-HPLC method was established for analysis of hordenine. Conditions for SPE, including volume of eluting solvent, pH of sample solution, sampling rate and sample volume, were optimized. The proposed SPE-HPLC method presented good linearity (R(2) = 0.9992) within 10-2000 ng/mL and the detection limits was 3 ng/mL, which is significantly more sensitive than reported methods. The method was also applied in plasma and urine samples; good capability of removing matrices was observed, while hordenine in low content was well extracted and enriched. The recoveries were from 90.6 to 94.7% and from 89.3 to 91.5% for the spiked plasma and urine samples, respectively, with the relative standard deviations <4.7%.

“…However, these techniques are time and/or labor intensive. The introduction of solid-phase extraction (SPE) and corresponding pre-packed commercially available columns enabled the application of high--throughput methods and robotics for fast and reproducible sample preparation, even when multiple steps must be introduced (47,48). Campone et al (49) introduced pressurized liquid extraction and online SPE coupled with ultra HPLC-MS/MS.…”

SummaryThe power of foodomics as a discipline that is now broadly used for quality assurance of food products and adulteration identifi cation, as well as for determining the safety of food, is presented. Concerning sample preparation and application, maintenance of highly sophisticated instruments for both high-performance and high-throughput techniques, and analysis and data interpretation, special att ention has to be paid to the development of skilled analysts. The obtained data shall be integrated under a strong bioinformatics environment. Modern mass spectrometry is an extremely powerful analytical tool since it can provide direct qualitative and quantitative information about a molecule of interest from only a minute amount of sample. Quality of this information is infl uenced by the sample preparation procedure, the type of mass spectrometer used and the analyst's skills. Technical advances are bringing new instruments of increased sensitivity, resolution and speed to the market. Other methods presented here give additional information and can be used as complementary tools to mass spectrometry or for validation of obtained results. Genomics and transcriptomics, as well as affi nity-based methods, still have a broad use in food analysis. Serious drawbacks of some of them, especially the affi nity-based methods, are the cross-reactivity between similar molecules and the infl uence of complex food matrices. However, these techniques can be used for pre-screening in order to reduce the large number of samples. Great progress has been made in the application of bioinformatics in foodomics. These developments enabled processing of large amounts of generated data for both identifi cation and quantifi cation, and for corresponding modeling.
