Beschreibung
Zusammenfassung:	In a method of separating phenylalanine and cinnamic acid from a mixed solution containing phenylalanine and cinnamic acid, a method of separating phenylalanine and cinnamic acid which comprises subjecting said mixed solution to chromatographic development using a synthetic adsorbent, such as Diaion, Amberlite etc., in the presence of a salt, such as ammonium halides, ammonium sulfate, alkali metal nitrates, ammonium and alkali metal salts of fatty acids, at a concentration in the range where the salting-out effect on cinnamic acid is greater than that on phenylalanine and also both phenylalanine and cinnamic acid can be dissolved, for example, in the range of 0.2-5N.
