Previous research suggested that solutions containing lithium chloride (LiCl) can extract gliadins more efficiently than can the traditional solvent, 70% ethanol. Those studies used sodium dodecyl sulfate (SDS) gel electrophoresis to compare extracted fractions. In this study, reversed-phase high-performance liquid chromatography (RP-HPLC) was used to further analyze and quantify such fractions. Results indicate that LiCl primarily extracts albumins, globulins, and omega-gliadins, while most alpha-, beta-, and gamma- gliadins, normally extracted with ethanol, are not solubilized.
