The stones from the fruits weigh about 9.5 g of which 58–67% is kernel. The kernels contain 40–58% oil. The fatty acid composition of the oil is: saturated fatty acids 13%, mono-unsaturated fatty acids 9%, licanic acid 44% and eleostearic acid 34%. Due to the high content of licanic acid (4-oxo-9,11,13-octadecatrienoic acid) and eleostearic acid, the oil is drying and solidifies rapidly into a varnish-like mass. The main commercial source of licanic acid is oiticica oil from ''Licania rigida'' Benth. from tropical America, which contains up to 80%. The presscake of ''Afrolicania elaeosperma'' remaining after oil extraction is not suitable as cattle feed.
