Abstract
From the epigeal part ofVerbascum georgicum Benth., in addition to aucubin, as the main component of the total iridoids a new iridoid has been isolated — 6-α-L-(4′-p-methoxy-trans-cinnamoyl)rhamnopyranosylcatalpol, the structure of which has been shown by UV, PMR, and mass spectroscopy and a comparison of the13C NMR spectrum with that of 6-α-L-rhamnopyranosylcatalpol (I). The presence of catalpol and (II) in the plant has been shown by PC and TLC.
