The paper investigates and recommends the multicomponent composition of cottonseed oil subjected to adsorption purification, divided into macro-and micro-impurities, according qualitative composition: substances that have an acidic, coloring unsaponifiable nature. authors come conclusion it is necessary develop a combined thermally differentiated capable purification on local activated sorbents.

Objective: To investigate the effects of avocado (A)/soybean (S) unsaponifiables on the metabolism of human osteoarthritic (OA) chondrocytes cultured in alginate beads over 12 days. Methods: Enzymatically isolated OA chondrocytes were cultured in alginate beads in a well defined culture medium for 12 days, in the presence or not of 10 10 M interleukin 1ß (IL-1ß). DNA content was measured using ...

Nowadays, data concerning the composition of Caryodendron orinocense Karst. (Euphorbiaceae) and Bactris gasipaes Kunth (Arecaceae) seed oils are lacking. In light of this fact, in this paper fatty acids and unsaponifiable fraction composition have been determined using GC-MS, HPLC-DAD (Diode Array Detector), NMR approaches and possible future applications have been preliminary investigated thro...

The amount and characterization of phytosterol and other minor components present in three Indian minor seed oils, mahua (Madhuca latifolia), sal (Shorea robusta) and mango kernel (Mangifera indica), have been done. Theses oils have shown commercial importance as cocoa-butter substitutes because of their high symmetrical triglycerides content. The conventional thin layer chromatography (TLC), g...

Gas-liquid chromatographic (GLC) determination of vitamin D in multivitamin preparations was investigated and a simple routine method was established. The unsaponifiable matters of a sample was applied to a thin-layer chromatography (TLC) plate using Kieselgel GF254 as an adsorbent and a mixture of n-hexane-ethyl acetate (4:1) as a developing solvent. The scraped zones corresponding to vitamin ...

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.
