Study of the seed oil of brachystegia nigerica hoyle and A.P.D. jones

Abstract

The characteristics of B. nigerica and its fixed seed oil are reported. Fatty acid composition, as determined by gas-liquid chromatography, was: lauric, 0.24%; myristic, 0.45%; palmitic, 13.18%; stearic, 19.80%; oleic, 20.84%; linoleic, 43.65%; arachidic, 1.14%; and arachidonic, 0.90%. A study of the nonsaponifiable fraction showed it to be rich in sterols. Ergosterol and sitosterol were identified. © 1990 American Oil Chemists' Society.
