title: Efficient extraction of bile acid conjugates with tetraheptylammonium chloride, a liquid ion exchanger.
abstract: Ethyl acetate or chloroform solutions of tetraheptylammonium chloride, an oil-soluble quaternary amine, quantitatively extract polar, anionic lipids such as steroid or bile salt conjugates from aqueous solution by a process of anion exchange.
