| Abstract: | Artemisia annua L. was extracted with supercritical CO_2 at different pressure, temperature and contact time to optimize the yield of artemisinin (QHS), which may achieve a yield well over 95% based on the content of QHS in the raw material A. annua L. The CO_2 extract can be simply purified with other separation method to obtain a final product with a purity over 99%. The authenticity of the product was verified by TLC, IR, MS, IHNMR and ~(13)CNMR. |
