OXIDATIVE PURIFICATION OF BIOMASS EXTRACTS CONTAINING PACLITAXEL 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.
