Abstract

In a chemosystematic investigation of Wulfeniopsis amherstiana we have isolated four common iridoid glucosides as well as the esters 3''- and 4''-Cinnamoyl 6-O-rhamnopyranosylcatalpol. Furthermore the plant contained mannitol, arbutin, and four caffeoyl phenylethanoid glucosides, namely plantamajoside, aragoside and two new acetyl derivatives of the latter, named amherstianoside A and B. From Lagotis integrifolia we have obtained mannitol and three common iridoid glucosides together with the 8,9-unsaturated iridoids arborescosidic acid and anagalloside. The results show that the genus Wulfeniopsis is chemically different from Wulfenia and that it is closer related to Veronicastrum.
