THE UNSAPONIFIABLE FRACTION FROM SPINACH FAT

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.

Anti-tumor effects of the glycolipids fraction from spinach which inhibited DNA polymerase activity.

We succeeded in purifying the fraction of monogalactosyl diacylglycerol (MGDG), digalactosyl diacylglycerol (DGDG), and sulfoquinovosyl diacylglycerol (SQDG) containing the major glycolipids from a green vegetable, spinach (Spinacia oleraceaL.). This glycolipids fraction inhibited the activities of replicative DNA polymerases (pols) such as alpha, delta, and epsilon, and mitochondrial pol gamma...
