Bioactive Compounds of Aboveground Organs Salicornia europaea L. of East Kazakhstan Flora

This study presents the phytochemical profile and antioxidant activity of the aboveground organs of Salicornia europaea L. collected from a natural population in East Kazakhstan. The chemical composition of the plant sample was studied using a complex of modern analytical methods, including HPLC, GC-MS, IR-Fourier spectroscopy, and elemental analysis. Metabolites were putatively annotated based on mass spectrometry data, corresponding to MSI level 2. It was found that the content of flavonoids was 2.40 ± 0.02 mg QE/g of dry raw materials, and the content of polyphenols was 6.73 ± 0.03 mg GAE/g. The antioxidant activity (ABTS test) reached 7.85 ± 0.04 mg TE/g. The concentration of fat-soluble and water-soluble vitamins was C—1.27 ± 0.12 mg/100 g, A—1.16 ± 0.11 mg/100 g and E—3.89 ± 0.38 mg/100 g. The IR characterization of plant raw materials and ash was carried out, the indicators of the elemental composition (TC, TOC, TIC, TN, TS) were determined. The totality of the obtained data indicates the phytochemical potential of Salicornia europaea L. growing in the territory of East Kazakhstan and may serve as a basis for further applied research.
