From the neutral fraction of an acetone extract of the roots of plants of the genusFerula,F. gummosa Boiss.,F. pseudoreoselinum Rgl. et Schmalh. (K-Pol.) andF. Samarkandica Eug. Kor., we have isolated a coumarin gummosin with the composition C24H30O4, mp 176–177°C, [a]D −54°C. The structure of gummosin corresponds to formula (III).
With respect to structure, gummosin is a spatial isomer of farnesiferol A; it differs from the latter by the fact that the secondary OH group in gummosin is axial.
