Oxidative purification of biomass extracts containing taxol and cephalomannine using ozone and girard reagents

摘要

A process for separating non-oxidizable compounds from a mixture containing at least one oxidizable compound. The mixture is contacted with ozone to oxidize oxidizable compounds to form oxidized compounds which are then converted to water-soluble hydrazones, followed by separation of the hydrazones from the mixture using precipitation, liquid/liquid extraction, chromatography, etc.
