Two new eudesmane-type glucopyranosides from the fruits of Daucus carota L.

Two new eudesmane-type glucopyranosides have been isolated from the fruits of Daucus carota L. On the basis of their spectroscopic and chemical evidence, the new compounds were elucidated as daucucarotol-10-O-β-D-glucopyranoside (1) and decahydro-7-[(2-O-β-D-glucopyranosyl)-isopropyl]-1β,4aα-dimethyl-(1α,4α,8aβ)-naphthalenetriol (2). Compounds 1 and 2 showed moderate antitumour activity against human ECA-109 and gave IC50 values of 23.22 and 26.76 μM, respectively.
