For this purpose, aerial plant parts were consecutively extracted with solvents of increasing polarity (dichloromethane, n-butanol, ethyl acetate), revealing that the A. atrata ethyl acetate fraction showed the highest antioxidant activity with an IC50 value of 12.2 \u00b1 0.29 \u00b5g\/mL compared to 17.0 \u00b1 0.26 \u00b5g\/mL for A. millefolium. Both species revealed the presence of luteolin, apigenin, centaureidin, and nevadensin exclusively in this most polar fraction, which are known as effective 2,2-diphenyl-picryl hydrazyl radical scavengers. The antioxidant capacity of the aforementioned fractions strikingly correlated with their total phenolic contents, which was highest in the ethyl acetate fraction of A. atrata. Characterization of the metabolite profiles of both Achillea species showed only marginal differences in the presence of key compounds, whereas the concentrations of individual compounds appeared to be species-specific. Our results suggest that A. atrata, based on its compound pattern and bioactivity characteristics, has similar qualities for phytotherapy as A. millefolium.<\/jats:p>","DOI":"10.3390\/molecules26061530","type":"journal-article","created":{"date-parts":[[2021,3,11]],"date-time":"2021-03-11T05:38:22Z","timestamp":1615441102000},"page":"1530","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Comparison of the Phenolic Compound Profile and Antioxidant Potential of Achillea atrata L. and Achillea millefolium L."],"prefix":"10.3390","volume":"26","author":[{"given":"Lysanne","family":"Salomon","sequence":"first","affiliation":[{"name":"WALA Heilmittel GmbH, Department of Analytical Development &amp; Research, Section Phytochemical Research, 73087 Bad Boll, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8664-0911","authenticated-orcid":false,"given":"Peter","family":"Lorenz","sequence":"additional","affiliation":[{"name":"WALA Heilmittel GmbH, Department of Analytical Development &amp; Research, Section Phytochemical Research, 73087 Bad Boll, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"Bunse","sequence":"additional","affiliation":[{"name":"WALA Heilmittel GmbH, Department of Analytical Development &amp; Research, Section Phytochemical Research, 73087 Bad Boll, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Otmar","family":"Spring","sequence":"additional","affiliation":[{"name":"Institute of Botany, Hohenheim University, 70599 Stuttgart, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian C.","family":"Stintzing","sequence":"additional","affiliation":[{"name":"WALA Heilmittel GmbH, Department of Analytical Development &amp; Research, Section Phytochemical Research, 73087 Bad Boll, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dietmar R.","family":"Kammerer","sequence":"additional","affiliation":[{"name":"WALA Heilmittel GmbH, Department of Analytical Development &amp; Research, Section Phytochemical Research, 73087 Bad Boll, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,11]]},"reference":[{"key":"ref_1","first-page":"157","article-title":"Role and regulation of plants phenolics in abiotic stress tolerance: An overview","volume":"Volume 1","author":"Khan","year":"2019","journal-title":"Plant Signaling Molecules: Role and Regulation under Stressful Environments"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Sharma, A., Shahzad, B., Rehman, A., Bhardwaj, R., Landi, M., and Zheng, B.
