Abstract
Two new alkyl coumarins, isophellodenol C (1) and candinol A (2); four new spirobifuranocoumarins, candibirins B–E (3-6); and two trifuranocoumarins, canditririns A and B (7 and 8), were isolated from the roots of Heracleum candicans WALL. Their structures were established using chemical and spectral means.
