Fatty acid content of selected seed oils.

Fatty acid content of selected seed oils from world-wide edible fruits, Ceratonia ciliqua (carob) from Caesalpiniaceae family, Diospyros kaki (persimmon) from Ebenaceae family, Zizyphus jujuba (jujube) from Rhamnaceae family, and Persea gratissima (avocado pear) from Lauraceae family, were determined by capillary gas chromatography- mass spectrometry (GC-MS) to find new natural sources for essential fatty acids. Among the seed oils analyzed, Ceratonia ciliqua has been found to have the highest essential fatty acid content.
