From an alcoholic extract of the roots of Ferula kokanica Rgl. et Schmalh., collected in the region of the village of Oman-kutan (Samarkand Province), have been isolated polyanthinin, mogoltadone, gummosin, kellerin, feshurin, and umbelliferone, and two new coumarins: deacetylkellerin, C24H32O5, M+ 400, mp 134-136 deg C, D22 +52 deg (c 0.1, ethanol), and kokanidin, C26H34O6, M+ 442, mp 189-191 deg C, D18 -30 deg (c 0.1, ethanol).The structure of deacetylkellerin has been established on the basis of the results of a study of UV, IR, PMR, and mass spectra.The structure and configuration of kokanidin have been established on the basis of spectral characteristics and also conversion into conferol acetate and feshurin.
