Here we investigated the influence of long-term strontium exposure (12 weeks, 0.5\u20134.0 mM Sr) on the content of phytoestrogens and allantoin as well as the mineral composition in soybean. Seven phytoestrogens were identified in the soybean: daidzin, glycitin, genistin, malonyldaidzin, malonylgenistin, daidzein, and coumestrol. The results showed that both malonyldaidzin and malonylgenistin were dominant phytoestrogens; however, the roots contained a relatively high amount of daidzein. It was found that strontium reduced the phytoestrogen content and decreased the antioxidant capacity. Strontium evoked depletion of the sum of all phytoestrogens by 40\u201370% in the leaves, 25\u201350% in the stems and in the seeds, depending on the strontium concentration. In the roots, 0.5 and 4.0 mM of strontium decreased the total phytoestrogen content by 25 and 55%, respectively, while 2.0 mM of strontium did not exert an effect on their accumulation. On the other hand, strontium ions induced allantoin accumulation mainly in the roots. Strontium was preferentially accumulated in the leaves, with a slight impact on macro- and micro-nutrients. Our research showed strontium-secondary metabolites interaction in the soybean, which can be useful for obtaining a natural pharmaceutical product containing both strontium and phytoestrogens for remediation of postmenopausal osteoporosis.<\/jats:p>","DOI":"10.3390\/ijms19123864","type":"journal-article","created":{"date-parts":[[2018,12,4]],"date-time":"2018-12-04T03:01:37Z","timestamp":1543892497000},"page":"3864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Effect of Long-Term Strontium Exposure on the Content of Phytoestrogens and Allantoin in Soybean"],"prefix":"10.3390","volume":"19","author":[{"given":"S\u0142awomir","family":"Dresler","sequence":"first","affiliation":[{"name":"Department of Plant Physiology, Institute of Biology and Biochemistry, Maria Curie-Sk\u0142odowska University, Akademicka 19, 20-033 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"W\u00f3jciak-Kosior","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Medical University of Lublin, Chod\u017aki 4a, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9346-6325","authenticated-orcid":false,"given":"Ireneusz","family":"Sowa","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Medical University of Lublin, Chod\u017aki 4a, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0039-4455","authenticated-orcid":false,"given":"Maciej","family":"Strzemski","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Medical University of Lublin, Chod\u017aki 4a, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5945-1047","authenticated-orcid":false,"given":"Jan","family":"Sawicki","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Medical University of Lublin, Chod\u017aki 4a, 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jozef","family":"Kov\u00e1\u010dik","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Trnava, Priemyseln\u00e1 4, 918 43 Trnava, Slovak Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Blicharski","sequence":"additional","affiliation":[{"name":"Orthopaedics and Rehabilitation Clinic, Medical University Lublin, Chod\u017aki 4a, Lublin 20-093, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1085","DOI":"10.2307\/3870059","article-title":"Stress-induced phenylpropanoid metabolism","volume":"7","author":"Dixon","year":"1995","journal-title":"Plant Cell"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"605","DOI":"10.1007\/s00299-007-0490-9","article-title":"Dynamics of phenolic acids and lignin accumulation in metal-treated Matricaria chamomilla roots","volume":"27","author":"Klejdus","year":"2008","journal-title":"Plant Cell Rep."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"4","DOI":"10.1016\/j.phytochem.2016.11.001","article-title":"Selected secondary metabolites in Echium vulgare L. populations from nonmetalliferous and metalliferous areas","volume":"133","author":"Dresler","year":"2017","journal-title":"Phytochemistry"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"12421","DOI":"10.1021\/jf3036319","article-title":"Effects of high-temperature stress on soybean isoflavone concentration and expression of key genes involved in isoflavone synthesis","volume":"60","author":"Chennupati","year":"2012","journal-title":"J.
