This invention belongs to the field of medicinal chemistry, specifically relating to a polysaccharide component from green plums, its preparation method, and its application. The invention first involves ethanol extraction of green plums (a dual-purpose medicinal and edible variety), separating the ethanol extract and the ethanol-extracted residue. The residue is then subjected to water extraction to remove protein, yielding a water-soluble crude extract. The ethanol extract and the water-soluble crude extract are then separated by macroporous adsorption resin column chromatography using pure water as the eluent, yielding a pure water eluent. The pure water eluent of the water-soluble crude extract is further fractionated and precipitated with alcohol to obtain different water-soluble polysaccharide alcohol-precipitated fractions. The ethanol-extracted polysaccharide component is obtained from the pure water eluent of the ethanol extract. The fractionated and ethanol-extracted polysaccharide components from green plums prepared using the method of this invention can be used to prepare drugs for the prevention and treatment of diabetes and kidney disease, exhibiting high safety and promising development and application prospects.
