Veronica Plants—Drifting from Farm to Traditional Healing, Food Application, and Phytopharmacology

“…From V. thymoides subsp. pseudocinerea , a new acylated flavone glucoside, 3′-hydroxyscutellarein 7- O -(6″- O -protocatechuoyl)-β-glucopyranoside (53), and a new phenol glucoside, 3,5-dihydroxyphenethyl alcohol 3- O -β-glucopyranoside were isolated, along with seven flavone, phenol, and lignan glycosides: 3′-hydroxyscutellarein-7- O -(6″- O -trans-feruloyl)-β-glucopyranoside (54), 3′-hydroxy, 6- O -methylscutellarein 7- O -β-glucopyranoside (55), luteolin 7- O -β-glucopyranoside (56), isoscutellarein 7- O -(6‴- O -acetyl)-β-allopyranosyl (1‴→2″)-β-glucopyranoside (57), 3,4-dihydroxyphenethyl alcohol 8- O -β-glucopyranoside (58), benzyl alcohol 7- O -β-xylopyranosyl (1″→2′)-β-glucopyranoside (59), and (+)-syringaresinol 4′- O -β-glucopyranoside (60) (Figure 10) [38].…”

“…Moreover, acylated flavonoids and phenol glycosides from V. thymoides subsp. pseudocinerea exhibited potent radical scavenging activity against DPPH radicals [38]. The two phenylethanoid glycosides, turrilliosides A and B, isolated from Veronica turrilliana Stoj.…”

Chemical profiling and cytotoxic activity of aqueous extract of Veronica peduncularis M.Bieb.: A chemotaxonomical approach

“…Additionally, there are various uses worldwide as an anticancer agent (Graham, Quinn, Fabricant, & Farnsworth, 2000), against hemoptysis, laryngopharyngitis, and hernia (Salehi et al, 2019), irregular menstruation, and embolism (Xue, Chen, Zhang, . Phytochemical studies on the genus Veronica showed the presence of many iridoid glycosides, most of which are benzoic and cinnamic acid esters of catalpol, in addition to the presence of phenylethanoids and flavonoid glycosides Saracoglu, Oztunca, Nagatsu, & Harput, 2011;Saracoglu, Varel, Harput, & Nagatsu, 2004). Biological activity studies on Veronica extracts showed their antimicrobial, antioxidant, cytotoxic, anti-tumour, antiinflammatory activities via in vitro and in vivo experiments (Harput, Saracoglu, Inoue, & Ogihara, 2002;Salehi et al, 2019).…”
