Abstract The thermodynamic and spectroscopic parameters of the betulin/2-hydroxypropyl-β-cyclodextrin (HPβCD) inclusion complex and its hepatoprotective activity were investigated in rats with nonalcoholic steatohepatitis (NASH). The pentacyclic triterpene betulin was isolated from birch bark and complexed with HPβCD. The parameters of inclusion complex formation were evaluated by infrared spectroscopy and differential scanning and isothermal titration calorimetries. The aqueous solubility and stability of betulin were significantly increased due to the formation of a stable inclusion complex with a stoichiometry of 1:1. The determined changes in molar enthalpy (ΔH 0) and free energy (ΔG
