“…Thus, plants of this genus exhibit antimicrobial [3], antioxidant [4], and anti-inflammatory [5] activity. According to the literature [6], the biological activity is related to the accumulation of highly active natural compounds such as flavonoids, iridoids, and phenolic acids and is due to their biogenesis in this plant group.…”

The macro-and microelemental composition of Euphrasia brevipila Burn. et Gremli (Scrophulariaceae) herbs and extracts was studied. Eighteen elements found in the herbs are arranged in the order of decreasing content as P > Mn > Ba > Sr > Zn > Ti > Ni > Cu > Zr > Cr > Co > Nb > V > Pb = Mo > Ga > Be > Ag. The quantitative order of the content of these elements decreased similarly in the preparations but the amount of each element was considerably smaller than in the herbs. The maximum degree of extraction (60 -100%) is typical of Nb, Zr, V, Ti, and Pb; a medium degree of extraction (20 -60%), Ni, Co, Cr, Cu, Ag, Mo, Ba, and Sr; and the lowest degree of extraction (0 -20%), Mn and Zn. All samples studied for heavy-metal content are in accordance with requirements of State Sanitary Rule 2.3.2.1078-01.

“…Pharmacological investigations of eyebright extracts revealed various types of biological activity, including hepatoprotector [4], hypotensive [5], antiinflammatory [6], antimicrobial [7] and antitumor properties [8]. The use of eyebright preparation for the treatment of eye disorders is also based on their regenerative and antioxidant properties, which are still insufficiently studied.…”

Fractions of biologically active substances, including polysaccharides, iridoids, phenolic acids, and flavonoids, have been isolated from eyebright (Euphrasia brevipila) plants (Scrophulariaceae family) by chromatography on a polyamide sorbent. The following compounds were identified: aucubin; chlorogenic, ferulic, and caffeic acids; apigenin; luteolin; diosmetin; cinaroside; and cosmosiin. The antioxidant activity of the isolated biologically active substances was assessed on the model of lanolin autooxidation at 70°C in comparison to butyloxytoluene. The maximum antioxidant activity was observed for the fraction of phenolic acids that produced a fourfold increase in the stability of lanolin with respect to oxidation.
