The compounds tested for ability to scavenge ABTS radical cations was in the order of ferulic acid &gt; coniferyl aldehyde \u2248 iso-ferulic acid &gt; ethyl ferulate \u2248 methyl ferulate. The results of the FRAP assay for ferulic acid, iso-ferulic acid, and coniferyl aldehyde were similar to and higher than those of methyl ferulate and ethyl ferulate. In the lipid system, iso-ferulic acid showed weak antioxidant activity. The other ferulates exhibited much stronger, yet similar, activities.<\/jats:p>","DOI":"10.3390\/molecules22040527","type":"journal-article","created":{"date-parts":[[2017,3,27]],"date-time":"2017-03-27T10:49:10Z","timestamp":1490611750000},"page":"527","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["The Structure\u2013Antioxidant Activity Relationship of Ferulates"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8313-3092","authenticated-orcid":false,"given":"Magdalena","family":"Karama\u0107","sequence":"first","affiliation":[{"name":"Department of Chemical and Physical Properties of Food, Institute of Animal Reproduction and Food Research, Polish Academy of Sciences, Tuwima 10, 10-748 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidiya","family":"Koleva","sequence":"additional","affiliation":[{"name":"Lipid Chemistry Department, Institute of Organic Chemistry with Centre of Phytochemistry, Bulgarian Academy of Sciences, Sofia 1113, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vessela","family":"Kancheva","sequence":"additional","affiliation":[{"name":"Lipid Chemistry Department, Institute of Organic Chemistry with Centre of Phytochemistry, Bulgarian Academy of Sciences, Sofia 1113, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9731-0045","authenticated-orcid":false,"given":"Ryszard","family":"Amarowicz","sequence":"additional","affiliation":[{"name":"Department of Chemical and Physical Properties of Food, Institute of Animal Reproduction and Food Research, Polish Academy of Sciences, Tuwima 10, 10-748 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1016\/B978-0-444-63473-3.00007-1","article-title":"The structure-activity relationships of plant secondary metabolites with antimicrobial, free radical scavenging and inhibitory activity toward selected enzymes","volume":"45","author":"Janeczko","year":"2015","journal-title":"Stud.
