![]() ![]() ![]() (formerly Derwentia species), and the New Zealand V. derwentiana is unique, since 6-O-esters of aucubin rather than of catalpol dominate, however.In a chemosystematic investigation of three Southern hemisphere species of Veronica, namely the Australian V. perfoliata is similar to that of Northern hemisphere species of Veronica because of the presence of characteristic 6-O-catalpol esters. Unusual iridoid glycosides in Veronica sects. The chemical profiles of the species were compared. The esters of cinnamic acid derivatives with iridoid and phenylethanoid glycosides and an unusually high concentration of verminoside were found to be the most distinctive chemotaxonomic characters of the sun hebes. The water-soluble compounds of Veronica pentasepala, Veronica raoulii and Veronica hulkeana were studied and 30 compounds including 15 iridoid glucosides, 12 phenylethanoid glycosides, the acetophenone. The sun hebes are a small clade of New Zealand Veronica formerly classified as Heliohebe. Iridoid and phenylethanoid glycosides in the New Zealand sun hebes ( Veronica Plantaginaceae) ![]()
