Abstract

The combustion enthalpy of diosgenin was determined by oxygen-bomb calorimetry. The standard mole combustion enthalpy and the standard mole formation enthalpy have been calculated to be −16098.68 and −528.52 kJ mol−1, respectively. Fusion enthalpy and melting temperature for diosgenin were also measured to be −34.43 kJ mol−1 and 212.33°C, respectively, according to differential scanning calorimetry (DSC) data. These studies can provide useful thermodynamic data for this compound.
