| Abstract: | The panlong seven was chopped up to remove the mud,with saturation limewater as extraction solvent,heated reflux 3 times for 4h each time,and then the extraction solution was concentrated to 1.15—1.20g/cm3 at constant pressure,while it was coolled to room temperature with pH value of 2—3.Rude production of bergenin was obtained under heated preservation of crystallization at 70℃,which was boiled to fading with 95% ethanol and active carbon.Then finishedgoods was obtained after filtering. |
