title: Phenylethanoid and iridoid glycosides in the New Zealand snow hebes (Veronica, Plantaginaceae).
abstract: Snow hebes are the alpine cushion-forming plants of New Zealand Veronica, formerly classified as Chionohebe. The chemical compositions of Veronica pulvinaris and Veronica thomsonii were studied and 33 water-soluble compounds were isolated. The structures of 14 previously unknown esters of phenylethanoid glycosides were elucidated by spectroscopic analyses. Further, eight known phenylethanoids, nine iridoids, 6'-feruloyl-sucrose and mannitol are also reported. It was found that the iridoid profile of the snow hebes was different from the other species of Veronica in New Zealand but similar to the alpine Northern Hemisphere representatives of the genus.
