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.

A process is described 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 include one or more of the classes alk(en)lyresorcinols, steroid, triterpenoid and cardiac glycosides and saponins, steryl ferulates and other phenolic acid conjugates, flavoroids, polar lipids, alcohol-soluble antimicrobials, prolamines and other alcohol-soluble proteolipids complexes. The process uses an aliphatic-substituted polysaccharide gel matrix in a process of hydrophobic interaction chromatography, and involves the steps of absorption, washing and recovery, wherein the extractives are absorbed and desorbed in the presence of and as a result of the concentration and selection of the organic ste of regenerating the gel matrix for further use.
