Pithecollobium dulce , Benth (syn. Inga dulcis , Willd) seed oil, belonging to the Leguminosae plant family, contains minor amounts of vernolic acid (12,13‐epoxy‐octadec‐ cis ‐9‐enoic acid, 10.0%), malvalic acid [7‐(2‐octacyclopropen‐1‐yl)heptanoic acid, 3.2%], and sterculic acid [8‐(2‐octacyclopropen‐1‐yl)octanoic acid, 2.0%]. The other normal fatty acids are palmitic (12.1%), stearic (4.2%), behenic (10.6%), oleic (34.1%), and linoleic (23.8%). These fatty acids have been characterized by Fourier transform infrared, 1 H nuclear magnetic resonance, mass spectrometry and gas‐liquid chromatography techniques and by chemical degradations.
