    摘要： Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, dissolving the starch in aqueous medium, molecular weight reduction by shearing, and optionally removal of residual water-soluble proteins, preferably by anion exchange chromatography. Purified starch and microparticles based on such starch.

    摘要： Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, subjecting the starch to a molecular weight reduction by acid hydrolysis, and optionally removing residual water-soluble proteins. Purified starch and microparticles based on such starch.

    摘要： A process for producing parenterally administrable microparticles, in which an at least 20% by weight aqueous solution of purified amylopectin-based starch of reduced molecular weight is prepared, the solution is combined with biologically active substance, an emulsion of starch droplets is formed in an outer phase of polymer solution, the starch droplets are med to gel, and the gelled starch particles are dried. A release-controlling shell is optionally also applied to the particles. Microparticles which essentially consist of said starch, have an amino acid content of less than 50 &mgr;g and have no covalent chemical cross-linking.
