Abstract Four new chromones, cnidimol C–F, along with cnidimol A, cnidimol B and karenin were isolated from the aerial parts of Cnidium monnieri . The structures of the new chromones were determined to be 5,7-dihydroxy-2-hydroxy-methylchromone, 5,7-dihydroxy-6-[(2 Z )-3-hydroxymethyl-2-butenyl]-2-hydroxymethylchromone, 5,7-dihydroxy-6-[2-hydroxy-3-methyl-3-butenyl]- 2-hydroxymethylchromone and 5,8-dihydroxy-2-hydroxymethyl-8-methyl-4 H ,9 H -pyrano [3,2- h ][1]benzoxepin-4-one.
