| Summary: | <b>Objectives</b>: The aim of this work was to determine the phenolic composition of sweet wormwood (<i>Artemisia annua</i> L., Asteraceae) from controlled cultivation in Serbia and to assess the potential antioxidant effects and cytotoxicity. <b>Methods</b>: High-performance liquid chromatography was used to determine the phenolic composition of <i>Artemisia annua</i> ethanolic extract. The antioxidant activity was studied using in vitro tests of inhibition of the neutralization of 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl (OH), and nitroso (NO) radicals, as well as the process of inhibiting lipid peroxidation and the ferric reducing antioxidant power (FRAP). The cytotoxicity was evaluated by the effect on three cell lines (the rat pancreatic insulinoma cell line (Rin-5F), the rat hepatoma cell line (H4IIE), and human hepatocellular carcinoma (Hep G2)) using the MTT test of viability. <b>Results</b>: Ethanol extract showed the highest potency in inhibiting the DPPH radical, and the half maximal inhibitory concentration (IC<sub>50</sub>) was 5.17 μg/mL. Chlorogenic acid was the dominant phenolic compound with an amount of 651 μg/g of dry extract. The results of the MTT viability test showed that the extract has the potential to inhibit the growth of the Rin-5F and Hep G2 cell lines, while no growth inhibition was observed on the H4IIE cell line. <b>Conclusions</b>: Undoubtedly, <i>Artemisia annua</i> is a powerful plant and a rich source of phenolic compounds. Inhibitory activity on causes of oxidative stress shows that the plant has a good antioxidant effect. Also, the anticancer activity shown through the inhibition of cell growth is not negligible. |
