Artemisinin is an effective antimalarial drug isolated from the herbal medicine Artemisia annua L. Supercritical fluid extraction is an environment-friendlymethod for the extraction of artemisinin. In thiswork, the solubility of artemisinin in supercritical carbon dioxide was determined by static method at three temperatures of 313K, 323 K, 333K and pressures from 11 to 31MPa. The range of experimental solubility datawas from0.498*10-3 to 2.915*10-3 mol/mol under the above-mentioned conditions.Two densitybased models (Chrastil and Mendez Santiago Teja models) were selected to correlate the experimental data of this work, and the average absolute relative deviation (AARD) was 8.32% and 8.33%, respectively. The correlation results showed good agreement with the experimental data.
