PURPOSE: A composition containing Youngia denticulate extract or compound isolated from the same are provided to induce activation of quinone reductase(QR) and to improve liver function. CONSTITUTION: A pharmaceutical composition for preventing cancer contains Youngia denticulate extract as an active ingredient, which is isolated using water, organic solvent or mixture solvent thereof. An organic solvent is alcohol of C1-C4, acetic acid ethyl, methylene chloride, or chloroform. The Youngia denticulate extract detoxifies carcinogen by enhancing quinone reductase activation. A pharmaceutical composition for preventing cancer contains Youngia denticulate fraction as an active ingredient. The Youngia denticulate fraction is obtained by frequently fractioning Youngia denticulate extract using n-hexane, ethyl acetate, and n-butanol. The pharmaceutical composition for preventing cancer contains a compound of chemical formula 1, 2, 3, 4, or 5 as an active ingredient.
