title: Two new guaiane-type sesquiterpenoids from the fruits of Daucus carota L.
abstract: Two new guaiane-type sesquiterpenoids containing an interesting epoxy unit, daucuside (1) and daucusol (2) were isolated from the fruits of Daucus carota L. Their chemical structures were elucidated on the basis of MS, NMR spectroscopic analyses coupled with chemical degradation and they were also evaluated for the cytotoxic effects against two human gastric cancer cell lines BGC-823 and AGS.
