title: A highly substituted germacranolide from Leontodon cichoraceus.
abstract: A re-investigation of subaerial parts of Leontodon cichoraceus (Ten.) Sanguin. yielded the new germacrane-type sesquiterpenoid 15-beta-D-glucopyranosyl-8-[p-(beta-D-glucopyranosyloxy)phenylacetyl]-salonitenolide. The structure was established by APCI mass spectrometry and 1D- and 2D-NMR spectroscopy. A survey by HPLC-DAD and HPLC-MS gave no signs of this compound in 23 other taxa of Leontodon.
