An annual Korean weed, Artemisia annua L., has been used as a folk medicine for the treatment of a number of diseases. Remarkably, among the 32 polyphenols characterized in various parts of plant tissue, including flowers, leafs, stems and roots, 10 compounds were detected for the first time using liquid chromatography–tandem mass spectrometry (LC/MS/MS). The quantification method was validated using structurally related external standards with determination coefficients ( R 2 ) ≥0.9995. The limits of detection and quantitation were 0.068–3.932 and 0.226–13.108 mg/L, respectively. The recoveries estimated at 50 and 100 mg/L ranged between 60.6–92.2 and 61.3–111%, respectively, with relative standard deviations <12%. The roots contained the largest concentration of identified components, while the flowers contained the least. The antioxidant capacity evaluated in terms of 1,1‐diphenyl‐2‐picrylhydrazyl and 2,2′‐azinobis(3‐ethylbenzothiazoline‐6‐sulfonic acid) radical cation‐scavenging activities and reducing power was highest in the roots and lowest in the flowers. The findings are well correlated and suggest that the antioxidant capacities principally depend upon the polyphenol concentrations in each part of the plant. Copyright © 2015 John Wiley & Sons, Ltd.
