摘要：
The antioxidant activity of ferulic acid (1), iso-ferulic acid (2), coniferyl aldehyde (3), methyl ferulate (4), and ethyl ferulate (5) were investigated using 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric-reducing antioxidant power (FRAP) assays and autoxidation of triacylglycerols of commercially available sunflower oil (TGSO). The compounds tested for ability to scavenge ABTS radical cations was in the order of ferulic acid > coniferyl aldehyde approximate to iso-ferulic acid > ethyl ferulate approximate to 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.
