Abstract: A method for preparing a polysaccharide containing arabinogalactan from Portulaca Oleracea L. is provided to improve production yield by about 2.5 times and to obtain a polysaccharide of specific molecular weight range. A method for preparing a polysaccharide containing arabinogalactan from Portulaca Oleracea L. comprises the steps of squeezing the cell wall of Portulaca Oleracea L.; mixing it with purified water and treating it with an enzyme to decompose the cell wall; reacting it with a proteinase to decompose the protein of Portulaca Oleracea L. into the one of small molecular weight; extracting it with hot water to obtain a water soluble fraction and removing insoluble precipitate; and adding an organic solvent to the water soluble fraction to obtain precipitate and centrifuging the precipitate to remove supernatant.
