Haemolytic saponin extraction and purification method

摘要

A saponoside mixture is immersed in an absolute ethanol bath at a temperature of 40-60 DEG C; a first rapid hot filtering step is performed in the bath at 40-60 DEG C to separate the polar and non-polar impurities from the dissolved saponins; the filtrate is cooled to cause precipitation thereof; a second filtering step is performed; and the saponin precipitate is dried in a vacuum oven at less than 40 DEG C.
