Adsorption resin AAS was used for the separation and purification of milupeinan (M-13)from its mother liquor. The good adsorption property of AAS adsorption resin was found formilupeinan (M-13) compared with the Diaion CHP 20p. When acetone and water (2:1 in volume)were used as desorption reagents, it was found that 3 times of bed volume of the desorption reagentswould make the AAS resin which was saturately adsorpted M-13 desorption completely.Also a macroporous anion exchange resin (Poly-4-vinylpyridine type) D-280 was used for thedecolourization from M-13 solution. Good results was given when the sr=1～2.
