Quantitative recovery of lecithins after argentation chromatography on thin layers

Abstract

The lecithins of rat liver are resolved into three fractions by chromatography on a thin layer of silica gel impregnated with silver nitrate. Each of these fractions is placed in a small column containing a cation-exchange resin, and the lecithins are eluted free from silver nitrate. Recoveries average 96%.
