A new coumarin glucoside, 8-hydroxy-5-O-beta-D-glucosylpsoralen, along with 17 known coumarins and one steroid, was isolated from the roots of
Heracleum rapula Franch. Four coumarin glucosides, including the new one, were obtained from the water-soluble fraction. The other coumarins isolated from the ethyl acetate-fraction included 10 furanocoumarins, a simple coumarin and three types of bicoumarins. Their structures were elucidated by means of spectroscopic analysis.
