Three coumarins, one chromone, and a phytosterol were isolated from the stem of Ostericum koreanum. Basis on the spectral data, we determined to be the structures of isolated compounds as bergapten, xanthotoxin, auraptenol, hamaudol, and mixture of phytosterols. Auraptenol was isolated for the first time from this plant.
