Evaluating the Isolation and Quantification of Sterols in Seed Oils by Solid-Phase Extraction and Capillary Gas–Liquid Chromatography

A faster and more efficient way of isolating and subsequently cleaning up the sterol fraction obtained from seed oils was developed based on an existing established method that used thin-layer chromatography (TLC) to isolate the sterol fraction (3). The newly developed method used solidphase extraction (SPE) to separate the sterol fraction from other compounds found in the unsaponifiable portio...

Sulfur Compounds: Gas Chromatography

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...
