Abstract
A new sesquiterpenoid, 1α,3α-dihydroxy-5,7,8,11αH-eudesm-4(15)-en-8β,12-olide (1), together with three known compounds, granilin (2), β-sitosterol (3), and β-daucosterol (4), was isolated from the ethanol extract of the flower buds of Carpesium triste. Their structures were elucidated by analysis of spectroscopic data, especially13C NMR and 1D NOE spectra.
