The unsaponifiable fraction of liver oils

Lxxvii. the Unsaponifiable Fraction of Liver

Nonsteroidal components of the unsaponifiable fraction of human liver.

In 1952 Penn (21) described the preparation of an unsaponifiable fraction of liver from cancerbearing patients which gave a serological reaction with sera of cancerous individuals, but usually not with normal serum or serum from persons with noncancerous diseases (12). The difficulty of ob taining sufficient stable test material for extensive cancer screening tests led to the development of a s...

The nature of the unsaponifiable fraction of the lipoid matter extracted from green leaves.

Isolation of geranyl geraniol from the unsaponifiable fraction of linseed oil.

From the unsaponifiable fraction (63 g) of linseed oil (25 kg), two terpenic alcohols were isolated by alumina column, thin-layer, and gas-liquid chromatography. They were identified as phytol and geranyl geraniol (a precursor of bi- and tricyclic diterpenes) by infrared and nuclear magnetic resonance spectroscopy, ozonolysis, and mass spectrometry.

Dietary oils high in oleic acid but with different unsaponifiable fraction contents have different effects in fatty acid composition and peroxidation in rabbit LDL.

OBJECTIVE We investigated the influence of different edible oils high in oleic acid but with different unsaponifiable fractions on the fatty acid composition and lipid peroxidation in plasma and low-density lipoprotein (LDL) in rabbits. METHODS Thirty-two rabbits were randomly assigned to four groups of eight animals. For 8 wk each group was fed a semisynthetic isoenergetic diet that differed...
