“…Saponins identified in E. campestre are interesting because of the acylation by a β,β-dimethylacrylic acid or angeloyl at the C-22 position, which is rare among triterpenoid saponins (Kartal et al, 2005;Kartal et al, 2006;Wang et al, 2012). A phytochemical analysis of the above-ground parts resulted in isolation and structural determination of flavonoids: quercetin, isoquercitrin, rutin, luteolin 7-O-β-D-glucopyranoside, astragalin, kaempferol 7-O-α-L-rhamnopyranoside, kaempferol 3,7-di-O-α-L-rhamnopyranoside, kaempferol-3-O-β-D-(2'-p-E-hydroxycinnamoyl)-glucopyranoside, kaempferol-3-O-β-D-(2'-p-Z-hydroxycinnamoyl)-glucopyranoside (Kartnig and Wolf, 1993;Hohmann et al, 1997;Wang et al, 2012). Simple coumarins: aegelinol benzoate, agasyllin, aegelinol and grandivittin occurred in the roots (Erdelmeier and Sticher, 1985;Wang et al, 2012).…”
