Abstract
From the pet. ether extract of S. sibiricum osthol, imperatorin, bergapten and a new coumarin named sibiricin have been isolated. It has been assigned 5,7-dimethoxy-coumarin-8-γ,γ-dimethylallyl epoxide structure on the basis of degradative and spectral studies. Final confirmation of the structure has been provided by a synthesis following an unambigous route using 3-dimethylallyl-2-hydroxy-4,6-dimethoxybenzaldehyde as the important intermediate.
