Complex Acetylenes from the Roots of Ferula communis.
The benzene extract from the roots of FERULA COMMUNIS afforded the coumarin ferulenol ( 1) and the structurally related acetylenes named ferulinolone [3-(1,2-dihydrofalcarinolonyl)-ferulenol] ( 4) and decarboxyferulinolone [2-nor-3-(1,2-dihydrofal-carinolonyl-ferulenol] ( 7). The structures of these substances were deduced from their spectral data and those of their derivatives, mainly from the (1)H- and (13)C-NMR 1D and 2D spectra (one bond and long-range correlations). Methoxylatifolone ( 10) was also isolated from this extract.
