Method for preparing crude saponin composition enhanced purity and effective saponin contents from platycodon grandiflorum or the extract therefrom

摘要

PURPOSE: A method for preparing a crude saponin compositions from Platycodon grandiflorum(Jacq.), A. DC is provided to enhance purity and active sponin content. CONSTITUTION: A method for preparing crude saponin compounds from Platycodon grandiflorum(Jacq.), A. DC or extract thereof comprises: a step of juicing Platycodon grandiflorum(Jacq.), A. DC or extracting Platycodon grandiflorum(Jacq.), A. DC with alcohol of C1-C3; a step of dissolving the extract in distilled water and applying to a reverse phase gel-filled column; a step of adsorbing sponin components; a step of eluting the sponin with an ethanol or methanol solution to obtain sponin; and a step of purifying the sponin using organic solvent.
