Corn hulls are composed of two major layers: the outer layer, the pericarp, is made up of non-living cell walls, and an inner layer, the aleurone, consists of a single layer of living cells, surrounded by thick cell walls. Dissected pure pericarp and aleurone fractions were ground and extracted with hexane and the yields and compositions of the resulting oils were examined. This study revealed that the high levels of ferulate-phytosterol esters and the high concentration of sitostanol previously reported in corn-fibre oil actually originate in the aleurone cells.
