Antioxidant polyphenolic acids in the medicinal herb feverfew ( Tanacetum parthenium ) were isolated through in vitro bioassay‐orientated antioxidant tests in response to 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH • ) free radical scavenging and Fe 2+ ‐chelating activities. Purification of the active compounds and their structural elucidation involved a variety of techniques including open‐column chromatography, HPLC, GC‐MS, LC‐MS and NMR. Major compounds with potent DPPH • scavenging activities were characterised as 3,5‐, 4,5‐ and 3,4‐di ‐O‐ caffeoylquinic acids (DCQAs). This is the first report of DCQAs found in feverfew.
