The method also covers direct analysis of the glufosinate metabolites 3-methylphosphinicopropionic acid (3-MPPA) and N-acetyl-glufosinate (NAG). The homogenized samples were extracted with 0.1% formic acid in water\u2013dichloromethane (50 + 50). The aqueous layer was derivatized with FMOC-Cl, cleaned through an HLB SPE cartridge, and determined by LC-MS\/MS. The sample size, extraction solvent, sample-to-solvent ratio, derivatization conditions,and cleanup procedure were thoroughly optimized, the LOQs of glyphosate, glufosinate, and AMPA were 0.5 ng\/g in grape, corn (leaf and seed), and cotton (leaf, seed, and oil) and 2 ng\/g in soybean and tea. The LOQs of NAGand 3-MPPA were 50 ng\/g in all the test matrixes, except tea and soybean, for which the LOQ was 100 ng\/g. Inall cases, average recoveries were &amp;gt;80%. The method successfully performed the estimation of glyphosate in incurred corn and cotton leaf samples collected from supervised field trials.<\/jats:p>","DOI":"10.5740\/jaoacint.17-0046","type":"journal-article","created":{"date-parts":[[2017,3,16]],"date-time":"2017-03-16T07:08:47Z","timestamp":1489648127000},"page":"631-639","source":"Crossref","is-referenced-by-count":37,"title":["Optimization and Validation of a Residue Analysis Method for Glyphosate, Glufosinate, and Their Metabolites in Plant Matrixes by Liquid Chromatography with Tandem Mass Spectrometry"],"prefix":"10.1093","volume":"100","author":[{"given":"Dasharath P","family":"Oulkar","sequence":"first","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandip","family":"Hingmire","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arnab","family":"Goon","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manjusha","family":"Jadhav","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bharat","family":"Ugare","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahammed Shabeer","family":"Thekkumpurath","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaushik","family":"Banerjee","sequence":"additional","affiliation":[{"name":"Indian Council of Agricultural Research, National Research Centre for Grapes, National Referral Laboratory, PO Manjri Farm, Pune 412 307, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,11,22]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/100\/3\/631\/32427951\/jaoac0631.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/100\/3\/631\/32427951\/jaoac0631.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,7,17]],"date-time":"2020-07-17T08:59:52Z","timestamp":1594976392000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/100\/3\/631\/5654205"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,5,1]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2019,11,22]]},"published-print":{"date-parts":[[2017,5,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.17-0046","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2017,5,1]]},"published":{"date-parts":[[2017,5,1]]}}}
