    摘要: Disclosed herein is a method for separating and purifying .alpha.-linolenic acid (ALA) from ALA-containing fatty acid mixtures by using a column chromatography, comprises the steps of: packing a column with silver nitrate(AgNO.sub.3)-impregnated silica gel as a stationary phase; passing the ALA-containing fatty acid mixtures through the column to adsorb the fatty acids to the stationary phase in the form of Ag.sup.+ -complexes; eluting the fatty acids with acetone-hexane mixtures; and collecting the fractions containing ALA having a purity of more than 95%.
