6-O-beta-glucopyranosylaucubin, a new iridoid from Odontites verna.
Fourteen iridoid glycosides have been isolated from Odontites verna ssp. serotina (Scrophulariaceae). In this paper the isolation of 6-O-beta-glucopyranosylaucubin is described; its structure and configuration has been demonstrated mainly by the aid of the (1)H- and (13)-C-NMR spectroscopy. The existence of a gamma glycosylation shift is showed.
