Aim. The profiles of polyphenolic phytochemicals in extracts of “hairy” roots of Artemisia tilesii Ledeb. and Artemisia annua L. were studied. Analytical separation and quantification of main components in extracts were evaluated.

Methods. “hairy” roots were grown in vitro on Murashige and Skoog medium. High-performance chromatography coupled with different types of detection (photo diode array detection (DAD) and electrospray ionization with ultra-high resolution Qq-Time-of-Flight mass spectrometry) was used to identify and quantify the main biologically active components in ethanol extracts of “hairy” roots.

Results. The amount of flavonoids was 94.71–144.33 mg RE/g DW and 33.52–78.00 mg RE/g DW in “hairy” roots of A. annua and A. tilesii, respectively. In most samples of “hairy” roots, the amount of flavonoids was higher than the content in the control plant roots. The presence of Apigenin (0.168 ± 0.003 mg/L and 0.178 ± 0.006 mg/L), Quercetin (0.282 ± 0.005 mg/L and 0.174 ± 0.005 mg/L) in the extracts of A. annua and A. tilesii was shown by reverse-phase HPLC-DAD method. Chlorogenic acid, Kaempferol, and other flavonoids were detected.

Conclusions. The developed HPLC-DAD method demonstrated the high percentage of recovery, low limit of detection and quantification (9,11 ng/ml ≤ LOQ ≤16,51 ng/ml), accuracy and correctness. Thus, the method is suitable for the simultaneous quantification of phenolic acids and flavonoids in various plant extracts with short time and high efficiency.

Key words: Artemisia tilesii, Artemisia annua, polyphenols, flavonoids, “hairy” roots, reversed-phase HPLC with diode matrix detector.
