Regional differences of lipid composition in morphologically distinct fatty tissues: III. Peanut seeds

Lipids extracted from three different parts of peanut seeds (cotyledons, germs, and hulls) have been examined for glyceride, fatty acid, and unsaponifiable composition. Notable differences have been shown, as expected, the unsaponifiable material being more abundant in germs than other parts of the seed. Germ oil, in turn, appears as more unsaturated. The presence of minor components, not detected when studying the unsaponifiable material from the whole oil, has been demonstrated. Besides qualitative distribution, the quantity of components of the unsaponifiable material has been shown to vary over wide limits in morphologically distinct parts of the seeds.
