Abstract: Purification conditions of eleostearic acid were primarily studied. The content of eleostearic acid was determined by gas chromatography. The main factors which affect eleostearic acid crystallization were studied by single factor test and uniform design test. The optimal condition for crystalliztion was 18 h at the temperature of -12℃ by acetone and the content of α-eleosteacric acid in purified product was up to 92.55%.

Key words: eleostearic acid, purification, uniform design test, GC
