Summary
Two iridoid glucosides, catalpol and aucubin, one
chlorinated iridoid aglycon, rehmaglutin D were isolated
from the iridoid fraction of the aerial parts of Plantago
lagopus L. together with the megastigman glucoside,
phlomuroside. The structures of the isolated compounds were
identified by means of spectroscopic (UV, HR-ESI, 1H-NMR,
13C NMR, HMQC, HMBC, COSY) methods. This is the first report
for the first isolation of rehmaglutin D and phlomuroside
from the genus Plantago.
Key Words :
Plantago, iridoid glucoside, rehmaglutin D,
phlomuroside, catalpol, aucubin.
