Abstract:
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.
Abstract:
PURPOSE: A composition containing extract and portions of southernwood wild plants as an active ingredient is provided to activate quinone reductase which is an indicator enzyme for preventing cancer and to activate an antioxidant response element by including extracts and portions of the southernwood wild plants including Adenocaulon himalaicum or Artemisia dubia. CONSTITUTION: A composition for preventing cancers contains extracts and portions of southernwood wild plants including Adenocaulon himalaicum and Artemisia dubia as an active ingredient. The extracts are obtained by extracting dried Adenocaulon himalaicum or Artemisia dubia using alcohol having a carbon number of 1-4 or a mixed solvent. The portions are n-hexane portions, ethylacetate portions, n-butanol portions, or water portions.
