NOVELTY - 4-Hydroxyphenethyl alcohol and beta -D-pentaacetylglucose are dissolved in methylene chloride, reacted, filtered, cooled, precipitated, and filtered, to obtain white solid. Activated charcoal is mixed with the solid, heated, and filtered. The resultant filtrate is added to solution of sodium methoxide in methanol, reacted, decolorized, filtered and concentrated. The resultant concentrate is extracted, the resultant aqueous phase is concentrated, extracted with solvent, concentrated and the resultant concentrate is recrystallized using organic solvent, to obtain salidroside.    USE - Preparation of salidroside (claimed).    ADVANTAGE - The method economically provides salidroside with high yield, by simple and environmentally-friendly process in a short period of time.    DETAILED DESCRIPTION - 4-Hydroxyphenethyl alcohol and beta -D-pentaacetylglucose are dissolved in methylene chloride solvent, and reacted at 15-50 degrees C for 0.5-5 hours under Lewis acid catalyst, to obtain reaction mixture. Aqueous sodium hydrogen carbonate solution is added to the obtained reaction mixture, mixed uniformly, filtered using diatomite filter, the resultant filtrate is washed using the methylene chloride solvent, organic solvent is added, mixed, cooled to 0 degrees C, precipitated, and filtered, to obtain white solid. Activated charcoal is added and mixed with the obtained white solid, heated, refluxed for 1 hour and filtered, to obtain filtrate. The resultant filtrate is added to solution of sodium methoxide in methanol, reacted at room temperature for 0.5-4 hours, acidic cation exchange resin is added, pH of the resultant solution is adjusted to neutral and filtered. Activated carbon is added and mixed with the resultant filtrate, decolorized at 70 degrees C for 1 hour, filtered, deionized water is added, and concentrated under reduced pressure, to obtain concentrate. The obtained concentrate is extracted with ethyl acetate 1-4 times, the resultant aqueous phase is separated, concentrated at 60 degrees C under reduced pressure, extracted with organic solvent 1-4 times, the resultant organic phase is concentrated under reduced pressure, and the resultant concentrate is recrystallized using organic solvent to obtain salidroside. The ratio of beta -D-pentaacetylglucose and 4-hydroxyphenethyl alcohol is 1:1-2.
