Abstract

A new dihydropyranocoumarin was isolated from the root of Peucedanum pareruptorum and the structure were established as 3’(R)-isobutyryloxy-4’(R)-acetoxy- 3’,4’-dihydroseselin (1) by spectroscopic methods. The absolute configuration was deduced by chemical correlations with known compounds.
