A Novel Purification Process for Homoharringtonine from Celphalotaxus koreana

An effective purification method was developed for producing Homoharringtonine (HHT), to guarantee high purity and yield from Cephalotaxus koreana. This process was a simple and efficient procedure, for the isolation and purification of HHT form the biomass of Cephalotaxus koreana, consisting of extract, adsorbent treatment, precipitation and followed by a chromatography. The extraction, adsorbent treatment and precipitation in pre-purification process allows for rapid and efficient separation of HHT from many compound and dramatically increases the yield and purity of crude HHT for HPLC purification steps compared to alternative processes. This purification processes serves to minimize solvent usage, size, and complexity of the operations for HHT purification.
