ABSTRACT
The heat capacities of artemisinin in crystal form were measured in the temperature range from 80 to 363K by an adiabatic calorimeter. Three thermal anomalies were observed at 198, 240, and 312 K. Thermogravimetry and differential thermal analysis from 300 to 700K showed melting at 420 K, loss of formic acid at 480 K, and further decomposition above 480 K.
