Abstract:
PURPOSE: A radiation radioprotective composition containing geraniin isolated from Nymphaea tetragona var. angusta extract fraction is provided to promote protection and recovery of hematopoietic system and to suppress oxidative cell damage. CONSTITUTION: A radiation radioprotective composition contains 0.001-10.0 weight% of geraniin as an active ingredient. The geraniin is isolated from Nymphaea tetragona var. angusta extract fraction. A method for isolating geraniin comprises: a step of preparing Nymphaea tetragona var. angusta in a powdery form and suspending with distilled water; a step of fractioning with hexane, ethyl acetoacetate, butanol, and water; a step of fractioning with methylene chloride, diethyl ether, ethyl acetate, and acetone; and a step of isolating geraniin by column chromatography.

Abstract:
A method for preparing a fraction concentrate of Elaeocarpus sylvestris var. ellipticus is provided to be able to obtain the fraction which is able to inhibit the lymphocyte damage by the radioactive rays irradiation and the apoptosis of tissue cells. A method for preparing a fraction concentrate of Elaeocarpus sylvestris var. ellipticus comprises the steps of: (a) after drying branch of Elaeocarpus sylvestris var. ellipticus in the shade, finely cutting it to prepare Elaeocarpus sylvestris var. ellipticus finely cut materials; (b) after precipitating the prepared cut materials in 70% ethanol at a temperature of 20-25 deg.C for 20-24 hours, filtering it using a filtering device under reduced pressure to prepare an ethanol extract; (c) concentrating the ethanol extract under reduced pressure to prepare a concentrate solution; (d) after suspending the concentrate solution with distilled water and putting 0.5-2 liters of hexane in 1 liter of the suspension with agitation, separating a hexane layer using a separatory funnel to obtain the remaining water layer; (e) after putting 0.5-2 liters of ethylacetate in 1 liter of the water layer with agitation, separating an ethylacetate layer using a separatory funnel; (f) concentrating the ethylacetate layer under reduced pressure to prepare an ethylacetate concentrate solution; and (g) after mixing the ethylacetate concentrate solution with sellaite and charging a column with the mixture, obtaining an ethylacetate fraction using ethylacetate as a developing solvent and then concentrating the fraction to obtain the fraction concentrate of Elaeocarpus sylvestris var. ellipticus.
