Chromatographic Identification of the Antilipæmic X Factor of the Unsaponifiable Fraction of Crude Vegetable Oils

Abstract

SEVERAL workers^1,2 hold that there is some unknown factor in crude corn oil and other vegetable oils which are more effective in lowering the elevated serum cholesterol and phospholipid levels in atherosclerosis rather than purified essential fatty acids alone. Jensen et al.³ reported that crude corn oil contains an unidentified nutritional factor which is more beneficial in increasing the egg weight and hatchability in the hen than essential fatty acids. Recently, Grande et al.⁴ have shown that there is a factor X present in the unsaponifiable fraction of crude corn oil, which can be taken as a better antilipæmic agent than purified essential fatty acids.
