Abstract

Snow hebes are the alpine cushion-forming plants of New Zealand Veronica, formerly classified as Chionohebe. The chemical composition of Veronica pulvinaris and Veronica thomsonii was studied and 33 water-soluble compounds were isolated. The structure 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.
