概要
From the dichloromethane extract of the roots of Peucedanum paniculatum L., two new coumarins, a species endemic to Corsica, have been isolated. Their structures were elucidated, on the basis of spectroscopic studies, particularly 1D and 2D NMR spectroscopy, as 6-(7'-beta-cyclolavandulyl)-7-hydroxycoumarin 1 and a spirodihydrofurano-coumarin 2 (Kallisteine A and B).
