On January 31, 2020, Ramos, Sara; Homem, Vera; Santos, Lucia published an article.COA of Formula: C24H27NO2 The title of the article was Analytical methodology to screen UV-filters and synthetic musk compounds in market tomatoes. And the article contained the following:
A Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) methodol. followed by gas chromatog.-tandem mass spectrometry (GC-MS/MS) anal. was developed to extract thirteen synthetic musk compounds (SMCs: cashmeran, celestolide, phantolide, traseolide, galaxolide, tonalide, musk ambrette, musk xylene, musk ketone, musk tibetene, musk moskene, ethylene brassylate and exaltolide) and six UV-filters (UVFs: 2-ethylhexyl 4-dimethylaminobenzoate, 3-(4′-methylbenzylidene) camphor, 2-ethylhexyl 4-methoxycinnamate, 2-ethylhexyl 2-cyano-3,3-diphenylacrylate, benzophenone and drometrizole trisiloxane) from tomatoes. The proposed methodol. was optimized: 2 g of freeze-dried tomato was extracted with 4 mL of water and 10 mL of Et acetate, adding 6 g of MgSO4 and 1.5 g of NaCl, then a dispersive solid-phase extraction was performed using 3 g of MgSO4, 300 mg of primary-secondary amino adsorbent (PSA) and 300 mg of octadecyl-silica (C18). Validation delivered recoveries between 81 (celestolide) and 119% (musk tibetene), with relative standard deviations <10%. The instrumental limit of detection varied from 0.02 (2-ethylhexyl 4-methoxycinnamate) to 3.00 pg (exaltolide and musk xylene). Regarding the method quantification limits, it ranged between 0.4 (celestolide) and 47.9 ng g-1 dw (exaltolide). The method was applied to different varieties of tomatoes (Solanum lycopersicum), revealing UVFs and SMCs between 1 and 210 ng g-1 dw. Higher concentrations were found for benzophenone (29-210 ng g-1 dw) and galaxolide (9-53 ng g-1 dw). The risk associated to the ingestion of contaminated tomatoes has also been estimated, showing that a potential health risk is unlikely. The experimental process involved the reaction of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate(cas: 6197-30-4).COA of Formula: C24H27NO2
