The practice of abusing antibiotics to improve livestock growth poses a threat to food safety. To prevent and regulate this, accurate monitoring of residual veterinary drugs (VDs) is required. A method based on QuEChERS with dispersive solid-phase extraction for the determination of multi-class VDs was investigated using selected product ions under optimized multiple reaction monitoring conditions. During the clean-up procedure, chitosan, octadecyl silica, primary-secondary amine, and enhanced matrix removal (EMR)-lipid were evaluated for simultaneous anal. of multi-class VDs in beef matrix. The EMR sorbent was most advantageous (113/115) compared to others, and showed a satisfactory recovery range (70.7-117.9%) except cefquinome (67.3%) and cefalonium (69.8%). This methodol. can be used to detect oxolinic acid and ractopamine (27.4% and 88.0% of maximum residue limit, resp.) in real beef samples. We thus study propose a simple and fast anal. method for multi-class VDs for the future health of humans and animals. In the experiment, the researchers used many compounds, for example, (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4HPLC of Formula: 328898-40-4).

A multiclass method for screening and confirmatory anal. of antimicrobial residues in milk has been developed and validated. Sixty-two antibiotics belonging to ten different drug families (amphenicols, cephalosporins, lincosamides, macrolides, penicillin, pleuromutilins, quinolones, rifamycins, sulfonamides and tetracyclines) have been included. After the addition of an aqueous solution of EDTA, the milk samples were extracted twice with acetonitrile, evaporated and dissolved in ammonium acetate. After centrifugation, 10 渭L were analyzed using LC-Q-Orbitrap operating in pos. electrospray ionization mode. The method was validated in bovine milk in the range 2-150 渭g kg-1 for all antibiotics; for four compounds with Maximum Residue Limits (MRLs) higher than 100 渭g kg-1, the validation interval has been extended until 333 渭g kg-1. The estimated performance characteristics were satisfactory complying with the requirements of Commission Decision 2002/657/EC. Good accuracies were obtained also taking advantage from the versatility of the hybrid mass analyzer. Identification criteria were achieved verifying the mass accuracy and ion ratio of two ions, including the pseudomol. one, where possible. Finally, the developed procedure was applied to thirteen real cases of suspect milk samples (microbiol. assay) confirming the presence of one or more antibiotics, although frequently the MRLs were not exceeded. The availability of rapid multiclass confirmatory methods can avoid wastes of suspect, but compliant, raw milk samples. In the experiment, the researchers used many compounds, for example, (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione).

This study was performed to optimize the anal. method for multi-residues of 60 compounds in flatfish samples. Three sample preparation methods were tested to identify the optimal recovery conditions for target analytes. As a result, 10 mL of water/acetonitrile (1:4, volume/volume) was used to extract analytes from fish samples. For purification, C18 and 10 mL of acetonitrile saturated hexane were used to treat the samples. After evaporation and reconstitution, the fish samples were analyzed by ultra-performance liquid chromatog.-tandem mass spectrometry. The proposed method was validated according to the CODEX guidelines (CAC/GL-71). Our results showed the recoveries of 73.2%-115% and coefficients of variation of 1.6%-22.1%. The limit of quantification was 0.0005-0.005 mg/kg in the fishery products. In anal. of real samples, no samples exceeded the limit of quantification. This anal. method can be used for multi-residue screening and confirmation of the residues of veterinary drugs in fishery products.

The piperidine ring can be found not only in more than half of the currently known structures of alkaloids, but also in many natural or synthetic compounds with interesting biological activities. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione

Multiclass Method for The Determination of 62 Antibiotics in Milk was written by Moretti, Simone;Cruciani, Gabriele;Romanelli, Sara;Rossi, Rosanna;Saluti, Giorgio;Galarini, Roberta. And the article was included in Journal of Mass Spectrometry in 2016.Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione This article mentions the following:

A multiclass method for screening and confirmatory anal. of antimicrobial residues in milk has been developed and validated. Sixty-two antibiotics belonging to ten different drug families (amphenicols, cephalosporins, lincosamides, macrolides, penicillin, pleuromutilins, quinolones, rifamycins, sulfonamides and tetracyclines) have been included. After the addition of an aqueous solution of EDTA, the milk samples were extracted twice with acetonitrile, evaporated and dissolved in ammonium acetate. After centrifugation, 10 μL were analyzed using LC-Q-Orbitrap operating in pos. electrospray ionization mode. The method was validated in bovine milk in the range 2-150 μg kg-1 for all antibiotics; for four compounds with Maximum Residue Limits (MRLs) higher than 100 μg kg-1, the validation interval has been extended until 333 μg kg-1. The estimated performance characteristics were satisfactory complying with the requirements of Commission Decision 2002/657/EC. Good accuracies were obtained also taking advantage from the versatility of the hybrid mass analyzer. Identification criteria were achieved verifying the mass accuracy and ion ratio of two ions, including the pseudomol. one, where possible. Finally, the developed procedure was applied to thirteen real cases of suspect milk samples (microbiol. assay) confirming the presence of one or more antibiotics, although frequently the MRLs were not exceeded. The availability of rapid multiclass confirmatory methods can avoid wastes of suspect, but compliant, raw milk samples. In the experiment, the researchers used many compounds, for example, (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione).

Comparison of sample preparation and determination of 60 veterinary drug residues in flatfish using liquid chromatography-tandem mass spectrometry was written by Kim, Joohye;Park, Hyunjin;Kang, Hui-Seung;Cho, Byung-Hoon;Oh, Jae-Ho. And the article was included in Molecules in 2020.Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione This article mentions the following:

This study was performed to optimize the anal. method for multi-residues of 60 compounds in flatfish samples. Three sample preparation methods were tested to identify the optimal recovery conditions for target analytes. As a result, 10 mL of water/acetonitrile (1:4, volume/volume) was used to extract analytes from fish samples. For purification, C18 and 10 mL of acetonitrile saturated hexane were used to treat the samples. After evaporation and reconstitution, the fish samples were analyzed by ultra-performance liquid chromatog.-tandem mass spectrometry. The proposed method was validated according to the CODEX guidelines (CAC/GL-71). Our results showed the recoveries of 73.2%-115% and coefficients of variation of 1.6%-22.1%. The limit of quantification was 0.0005-0.005 mg/kg in the fishery products. In anal. of real samples, no samples exceeded the limit of quantification. This anal. method can be used for multi-residue screening and confirmation of the residues of veterinary drugs in fishery products. In the experiment, the researchers used many compounds, for example, (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione (cas: 328898-40-4Recommanded Product: (4R,5S,6S,7R,9R,11E,13E,15R,16R)-6-(((2R,3R,4S,5S,6R)-4-(Dimethylamino)-3,5-dihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)-16-ethyl-4-hydroxy-5,9,13-trimethyl-7-(2-(piperidin-1-yl)ethyl)-15-(piperidin-1-ylmethyl)oxacyclohexadeca-11,13-diene-2,10-dione).
