Abstract: Three new phenolic compounds were isolated from the aerial parts of Globularia alypum. Their structures were determined as 6-hydroxyluteolin 7-O-laminaribioside (1), eriodictyol 7-O-sophoroside (2), and 6'-O-coumaroyl-1'-O-[2-(3,4-dihydroxyphenyl)ethyl]-beta-D-glucopyranoside (3). In addition, three phenylethanoid glycosides (acteoside, isoacteoside, and forsythiaside) and two flavonoid glycosides (6-hydroxyluteolin 7-O-beta-D-glucopyranoside and luteolin 7-O-sophoroside) were also isolated and are reported here for the first time in this plant. The structures of compounds 1-3 were established on the basis of their spectroscopic data analysis. Evaluation of the antioxidative activity, conducted in vitro, showed that the isolated phenylethanoids and flavonoid glycosides possess strong effects of this type.
