Iridoid and phenylethanoid glycosides in the New Zealand sun hebes (Veronica; Plantaginaceae)

► Thirty compounds were isolated and identified from three species of Veronica. ► The iridoids dihydroverminoside and α-truxillic acid catalpyl diester were isolated. ► The species in the group accumulated unusually high levels of verminoside. ► Carbohydrates, iridoids and phenylethanoids were used as chemotaxonomic markers.
