In order to solve the problem of conservation and increase diversity of Artemisia (L.) genus plants itʼs necessary to determine their biologically active compounds and benefit on human health [1], [3]. Different studies indicate positive effects of Artemisia extracts and essential oils for the treatment of malaria, cancer, inflammation and infections by fungi, bacteria and viruses such as SARS-CoV-2 [1], [2].

The object of investigation was Artemisia pontica (L.) – a medicinal (aromatic) plant of Asteraceae (Bercht. & J. Presl) family, introduced in the Middle of Lithuania since 1973.

The aim of this study was to determine qualitative and quantitative phenolic content and antioxidant activity in Artemisiae pontici herbae samples were collected at different vegetation stages.

The methanolic Artemisiae pontici herbae extracts reported the highest total phenolic (271.93 ± 2.54 RE mg/g), FRAP (62.17 ± 0.32 µmol TE/g DW) and CUPRAC (152.94 ± 3.42 Μm TE/g) amount in massive flowering vegetation stage. Moreover, the highest value of total amount of flavonoids (8.56 ± 0.09 RE mg/g) and DPPH (87.26 ± 0.30 RE mg/g) were determined in the end of flowering, ABTS•+ (85.57 ± 0.89 µmol TE/g DW) in the beginning of flowering. The following phenolic acids and flavonoid glycosides were identified (caffeic, chlorogenic, neochlorogenic, 4,5-dicaffeoylquinic, 4-O-caffeoylquinic, 3,5-dicaffeoylquinic, 3,4-dicaffeoylquinic, isorhamnetin-3-rutinoside, luteolin-7-O-glucoside, luteolin-7-rutinoside, rutin. The significantly higher (p < 0.05) amount of chlorogenic (188.04 ± 0.81 mg/g) and 3,5-dicaffeoylquinic acid (122.16 ± 2.12 mg/g) were detected in the intensive growth vegetation stage.
