Abstract:
PURPOSE: A method for preparing a rice bran-derived glycoprotein fraction and a composition containing the fraction for enhancing immunity are provided to promote NO and TNF-alpha generation. CONSTITUTION: A rice bran-derived glycoprotein fraction comprises: a step of defatting rice bran; a step of mixing the rice bran in a buffer solution of pH 7.0-8.0; a step of centrifuging the mixture to obtain supernatant; a step of performing dialysis of the supernatant using dialysis semipermeable membrane; a step of adding salt to precipitate glycoproteins; a step of dissolving the precipitate in a buffer solution of pH 7.0-8.0 and performing dialysis with the dialysis semipermeable membrane; and a step of freeze-drying the dissolved precipitate. A composition for enhancing immunity contains the glycoprotein fraction as an active ingredient. A pharmaceutical composition for preventing or treating cold, atopy, chronic fatigue, or cancer contains the fraction as an active ingredient.
Abstract:
The present invention relates to a fraction of rice wine lees derived-glycoprotein, which is characterized in having a molecular weight of 15 to 110 kDa, and a method of producing the same and, more specifically, to a fraction of rice wine lees-derived glycoprotein and the uses thereof, which is prepared by a method comprising: (a) a step of removing fat in rice wine lees; (b) a step of mixing the rice wine lees in a buffer solution having a pH level of 7.0 to 8.0; (c) a step of obtaining a supernatant by centrifugation; (d) a step of dialyzing the supernatant with a dialysis semipermeable membrane (MWCO 6000-8000); (e) a step of adding a salt precipitating protein in the dialyzed supernatant to precipitate glycoprotein; (f) a step of dissolving the precipitate in a buffer solution having a pH level of 7.0 to 8.0 with a dialysis semipermeable membrane (MWCO 6000-8000); and (g) a step of obtaining a fraction of glycoprotein from the dialyzed and precipitated lysate. The fraction of glycoprotein of the present invention has a better effectiveness of promoting histiocyte vitality than Krestin (PSK), which is a medicine for enhancing immune vitality, and has no cytotoxicity, thereby being effective in producing a new functional food and a medicine for enhancing immune function.
