Abstract

Objective: Terminalia chebula fruits are used as traditional herbal medicine from ancient era but still now, extract has not revealed any research data on CNS depression activity as well as its lyophilized herbal formulation. The present study was designed to evaluate CNS depression activity and develop lyophilized oral cake of Terminalia chebula fruit extract.


              


Methods: CNS depression potential of Terminalia chebula fruits was examined using hole board, hole cross and thiopental sodium induced sleeping time test. Human equivalent dose was calculated based on US FDA guidelines of dose conversion between animals and human. A novel lyophilized herbal oral cake of aqueous extract of Terminalia chebula fruits with additives was then formulated. The formulated cake was subjected to characterize its physicochemical properties such as appearance, residual humidity, drug content, dissolution and drug release profile, extract-polymer compatibility by Fourier-transform infrared spectroscopy (FTIR) and stability. Prepared cake was further evaluated with hole board and hole cross model in mice and compared with control to ensure its CNS depression activity.


 


Results: Crude extract at the doses of 100, 150, 200 and 400 mg/kg body weight showed significant (p<0.01) dose dependent inhibition of locomotors behavior. Crude extract dose of 200 mg/kg body weight in mice comparable with standard diazepam dose (1 mg/kg) was used to calculate human equivalent dose of 1000 mg/60 kg. Formulation presented rapid drug release profile while drug content was approximately 99.5%. FTIR spectroscopy of formulation showed no drug-excipient interaction. The oral cake at the dose of 200 mg/kg body weight showed significant (p<0.01) CNS depression activity.


 


Conclusion: CNS depression activity, FTIR and stability analysis ensures preservation of active ingredients in lyophilized oral cake as in crude extract.

Keywords: Terminalia chebula, lyophilized herbal formulation, Fourier-transform infrared spectroscopy (FTIR), locomotors movement
