The component fatty acids of Psidium guajava seed fats

Abstract

The seed fat of Psidium guajava has been analysed by thin-layer and gas-liquid chromatographic methods. The lipids, made up exclusively of neutral lipids, mostly triglycerides, accounted for 9.4% of the dry weight of the seeds. G.l.c. revealed that the seed fat is linoleic acid-rich (79 %); palmitic, oleic and stearic acids being the other minor acids present. There are neither percentage nor compositional differences in the fatty acids at different stages of development of the seeds.
