“…The methodology is greatly useful to the study of metabolic variations induced by genetic mutations or by dysfunctions of protein activity occurring in some pathologies (29,30) or to monitor the levels of an analyte in biofluids included the absorption of some drugs. There are numerous studies demonstrating the versatility of the MRM/MS applications in food field not only for a molecular investigation of organoleptic and nutritional properties and of possible contaminants (31,32) but also for the study of variations following particular treatments or different ripening stages (33)(34)(35).…”

This work focused on the extraction, quantification, and characterization of bioactive compounds of Arbutus unedo L. fruits, comparing the results obtained from the different ripening states. Extractions were performed by different methods (such as maceration extraction and ultrasonic extraction) and food grade solvents (aqueous and hydroalcoholic solvents) in each of the all ripening states (four states considered, associated with four different colors, i.e., green, yellow, orange, and red). The presence of (poly)phenols was quantified and characterized, and scavenging activity was determined by the Folin–Ciocâlteu reagent and the DPPH method, respectively. The content of bioactive compounds was characterized by LC-MS/MS, such as multiple reaction monitoring (MRM) mass spectrometry. The results showed that ultrasound-assisted extraction (UAE) performed better than maceration extraction; ethanol–water mixture extracts showed a more positive effect than the use of aqueous extracts regarding the content of total phenolic compounds. Overall, the total phenolic compounds in the EtOH:H2O mixture at a ratio of 7:3 (v:v) were higher than that of the other solvents for both extraction methods. Some bioactive molecules were characterized for the first time in the extracts of A. unedo. The chemical profile of the strawberry tree extracts depended on the degree of fruit ripeness. The results suggest that A. unedo fruits may be of great interest for food and nutraceutical applications.

“…These fast GC methods are not compatible with MS detection, Q [40]. All these chromatographic approaches combined with the rapid treatment of samples are the ones sought to achieve more and better analyses, especially in the analysis of multiple residues in different agri-food matrices [41,43,44] Liquid chromatography (LC) is mainly used for the analysis of high molecular weight, very polar and/or thermally labile compounds [45,46].This technique is known as a complement to GC for pesticide analysis. Reverse phase (RP) and pre-columns (C8 or C18) with mobile phases composed mainly of water and methanol (MeOH) or acetonitrile (ACN), using ultraviolet light (UV) or diode array (DAD), have been developed in detection systems is the MS, the MS/MS that is the most used for the analysis of pesticides when it is coupled to HPLC [47,48].…”

The growing production and use of multiple types of pesticides in the agri-food sector has caused strong concern on the part of many organizations worldwide, which question the degree of safety and quality of the products being supplied to the population. Colombia, a geographically privi-leged country with extensive areas of agricultural use, is not apathetic to this situation. Therefore, this review article aims to give a citrus and updated vision of the use of pesticides worldwide and subsequently in the Colombian agricultural sector. As a result, a sector that is currently growing and contributing to the national economy was identified. However, with a strong tendency to use pesticides to maximize production yields and minimize associated costs. Currently, many pesti-cide residues are identified in transitional and high value crops, such as vegetables and fruits. This causes chronic and/or acute intoxication scenarios in populations that meet these substances. Finally, academia and the public sector seek to update knowledge that promotes the regulation and management of this type of substances, promoting the transformation of the sector towards organic and regenerative agri-food models that prohibit the implementation of pesticides for pest and disease control.

“…It is easy to find monofamily methods for the determination of phytohormones (auxins [ 10 , 11 ], cytokinins [ 12 , 13 ], gibberellins [ 14 , 15 ]) or methods specifically developed for the analysis of acidic herbicides [ 16 , 17 , 18 ] in the literature. Some scientific publications have even jointly analyzed various families of phytohormones [ 19 , 20 , 21 , 22 , 23 , 24 ].…”

A 7-min multifamily residue method for the simultaneous quantification and confirmation of 8 phytohormones and 27 acidic herbicides in fruit and vegetables using ultra high-performance liquid chromatography (UHPLC) coupled to tandem mass spectrometry (MS/MS) was developed, validated according to SANTE 12682/2019, and accredited according to UNE-EN-ISO/IEC 17025:2017. Due to the special characteristics of these kinds of compounds, a previous step of alkaline hydrolysis was carried out for breaking conjugates that were potentially formed due to the interactions of the analytes with other components present in the matrix. Sample treatment was based on QuEChERS extraction and optimum detection conditions were individually optimized for each analyte. Cucumber (for high water content commodities) and orange (for high acid and high water content samples) were selected as representative matrices. Matrix-matched calibration was used, and all the validation criteria established in the SANTE guidelines were satisfied. Uncertainty estimation for each target compound was included in the validation process. The proposed method was applied to the analysis of more than 450 samples of cucumber, orange, tomato, watermelon, and zucchini during one year. Several compounds, such as 2,4-dichlorophenoxyacetic acid (2,4-D), 4-(3-indolyl)butyric acid (IBA), dichlorprop (2,4-DP), 2-methyl-4-chlorophenoxy acetic acid (MCPA), and triclopyr were found, but always at concentrations lower than the maximum residue level (MRL) regulated by the EU.
