Two new xanthyletin-type coumarins were isolated from the root of Peucedanum decursivum and the structures were established as 3′(S),4′(R)-biangeloyloxys-3′,4′-dihydroxanthyletin and 3′(S)-senecioyloxy-4′(R)-angeloyloxy-3′,4′-dihydroxanthyletin, respectively, by spectroscopic methods. The absolute configurations were deduced by chemical correlations with known compounds.
