| description | The invention discloses a method for obtaining rose glycoside through low-frequency ultrasound. The method comprises the following steps: (1) pretreating raw materials; (2) ultrasonically extracting the raw materials; (3) treating a mixed solution; (4) treating an extracting solution; and (5) decoloring and refining. Roses are dried and crushed, the contact area of the roses and an extracting agent is enlarged, and the extraction rate of the rhodoside is increased. Meanwhile, polyethylene glycol-ammonium sulfate-water is used as an extracting agent, effective components such as volatile oil, monoterpenoids, polyphenols and alkaloids in the roses can be brought out, polyethylene glycol can be removed through reduced pressure evaporation, no organic solvent is left, and safety is guaranteed. And dissolving the extracting solution in a mixed solution of ethanol and sodium chloride, and rapidly passing through the cationic cellulose at room temperature, so that the impurity protein is adsorbed on the cationic cel |
