MUSHROOM PROTEIN FOR FOOD AND BEVERAGE EFFECTIVE IN PREVENTING AND TREATING HYPERTENSION AND HYPERLIPEMIA AND HAVING ANTITUMOR ACTION, MUSHROOM PROTEIN FOR FOOD AND BEVERAGE EFFECTIVE IN PREVENTING AND TREATING OBESITY AND HAVING ANTITUMOR ACTION AND METHOD FOR EXTRACTING THESE PROTEINS

摘要

PURPOSE: To obtain a mushroom protein having about 40000 molecular weight, exhibiting excellent suppressing action on elevation of blood pressure and serum lipid and further exhibiting vasodepressor activity against hypertension and serum lipid lowering activity against hyperlipemia when ingested as a food or beverage, or a mushroom protein having about 13000 molecular weight, having suppressing action on increase of body weight, further, having weight reducing action and unstable to heat. ;CONSTITUTION: An extract solution obtained by extracting a fruit body or hypha of Grifola frondosa or Flammulina velutipes with water is dialyzed and the dialyzed solution is subjected to ion exchange chromatography and eluted with sodium chloride and further salted out and the deposited material is dissolved in water and the solution is subjected to gel permeation chromatography. Thereby, an active fraction having about 40000 molecular weight and an active fraction of about 13000 molecular weight are fractionated by gel permeation chromatography.;COPYRIGHT: (C)1996,JPO
