    摘要: A process is described for the preparation f electrostatically-linked, aliphatic- or alicyclic-substituted anionic or cationic polysaccharide gels from readily available macroporous ionic polysaccharide chromatographic media, such as diethylaminoethyl (DEAE), quaternary aminoethyl (QAE) and sulfopropyl (SP) substituted polysaccharide gels. These novel gels are used for the isolation, recovery and purification of non-polar extractives using one or more extracting solvents from the group of lower alcohols, ketones, and water. The non-polar extractives may be alk(n)lyresorcinols, steroid, triterpenoid, cardiac glycosides and saponins, steryl ferulates and other phenolic acid conjugates, flavonoids, lipids, alcohol-soluble antimicrobials, prolamines or other alcohol-soluble proteolipid complexes.

    摘要: A method for making an ion exchange coating (e.g., a chromatographic medium) on a substrate comprising (a) reacting at least a first amine compound comprising amino groups, with at least a first polyfunctional compound, in the presence of a substrate to form a first condensation polymer reaction product, with a first unreacted excess of either at least said first amino group or polyfunctional compound functional moieties, irreversibly attached to the substrate, and (b) reacting at least a second amine compound or at least a second polyfunctional compound with unreacted excess in the first condensation polymer reaction product to form a second condensation polymer reaction product, and repeating the steps to produce the desired coating. A coated ion exchange substrate so made.
