    The present invention relates to the purifying process of general ginsenoside with several kinds of resin .The purifying process includes utilizing the first resin to adsorb water solution of coarse ginsenoside to eliminate water soluble impurities and desorbing the absorbed resin with organic solution or its water solution; and utilizing the second and the third kinds of resin to adsorb impurity selectively from the organic eluent of ginsenoside. The first resin is polar adsorbing resin, the second is strong alkali resin and the third is non-polar adsorbing resin. The said purifying process has great purifying capacity, complete elimination of impurity and high ginsenoside yield, up to 90%. The purifying process has ginsenoside content in the product up to 92% and ginsenoside yield up to 90%.
