【正文】 carried out the Sophora japonica with 30 minutes .then filtering the solution and carried out the residue in the ultrasonic cleaner again. Collecting the filtrate in beaker and Adjusting the filter’s PH to 3 with concentrated hydrochloric acid. Standing the filter and precipitating pletely. Collecting the precipitate by the filtration. The precipitate is crude extract rutin. Recrystallizating the crude extract rutin in 6070 ℃ water bath and boiling the recrystallizate’s solution on electric furnace with 15 minutes. Filtrating the solution when it is boiling and the filtrate aside until the precipitate pletely. Filtrating the solution, Then collecting the precipitate. The precipitate dried at 65 ℃ in Vacuum oven with40 minutes . Getting the purified rutin. Alkali solution and acid precipitation is soaked Sophora japonica with distilled water, Adding calcium oxide g. adjusting the PH to 8, Boiling the Solution with 30 minutes, then filtering the solution and carried out the residue again, Collecting the filtrate in beaker and Adjusting the filter’s PH to 5 with concentrated hydrochloric acid. Standing the filter and precipitating pletely. Collecting the precipitate by the filtration. The precipitate is crude extract rutin. Recrystallizating the crude extract rutin in 6070 ℃ water bath and boiling the recrystallizate’s solution on electric furnace with 15 minutes. Filtrating the solution when it is hot and the filtrate aside until the precipitate pletely. Filtrating the solution, then collecting the precipitate.
