METHOD FOR PRODUCING PROANTHOCYANIDIN POLYMER COMPOSITIONS FOR PHARMACEUTICAL FORMULATIONS

摘要

Processes for producing pharmaceutical compositions containing a proanthocyanidin polymer useful for the treatment and prevention of various conditions are provided. The invention specifically relates to processes for producing pharmaceutical formulations of a proanthocyanidin polymer composition which has been isolated from a Croton spp. or a Calophyllum spp. In particular, the invention relates to a process for producing proanthocyanidin polymer compositions which achieve concentrations and purities useful for addition to pharmaceutically effective formulations.
