【Abstract】 Influential factors on extracting platycodins with water were investigated systematically, on which the method was based for preparing platycodins by water\|extracting and macroreticular resin column chromatography\|separating. That is, to the powder of Radix platycodonis , added altogether 20\|fold water (W/W) and refluxed three times with 0.5 hour for each time. The filtrate was then passed through the macroreticular resin and platycodins were obtained by gradient eluation using water and alcohol as elution system. The average gaining rate of platycodins was 1.603 %. The method offers a basis of industrialized production of platycodins for its advantages of easy, rapid operation, and low cost.更多还原
