Beschreibung
Zusammenfassung:	The invention relates to a preparation method of a wheat germ extract rich in spermidine, which is characterized in that the method realizes preparation of the wheat germ extract rich in spermidine from wheat germs by using macroporous adsorption resin combined with a silica gel column chromatography technology. The method provides an optimal choice for preparing the wheat germ extract rich in spermidine for a raw material with the highest content of spermidine in plants, adopts ethanol as an extraction solvent, is simple, common, easy to obtain and safe, and greatly reduces the extraction cost compared with other carbon dioxide supercritical fluid, trichloroethanol and the like. According to the method, the processing process is simple, the preparation time is short, the extraction rate is high, thermal degradation of heat-sensitive components can be effectively avoided, the spermidine content in the obtained wheat germ extract is 2120 times that of wheat germs, the cost can be effectively reduced, and the s
