PROCESS FOR PURIFICATION OF ARTEMISININ AND OTHER CONSTITUENTS FROM ARTEMISIA ANNUA IN HIGH YIELD AND HIGH PURITY

摘要

The present invention discloses a novel hybrid process for the extraction and purification of artemisinin and other constituents from Artemisia annua. The process involves the solid- liquid extraction and chromatographic purification coupled with refining by bleacher followed by evaporative crystallisation to give the artemisinin with yield of >90% and HPLC assay purity of >99%.
