Extraction and Characterization of Boswellia Serrata Gum as Pharmaceutical Excipient.

BACKGROUND

This manuscript deals with the purification and characterization of Boswellia serrata gum as a suspending agent. The Boswellia serrata gum was purchased as crude material, purified and further characterized in terms of organoleptic properties and further micromeritic studies were carried out to characterize the polymer as a pharmaceutical excipient. The suspending properties of the polymer were also evaluated. The results showed that the extracted gum possesses optimum organoleptic as well as micromeritic and suspending properties.

OBJECTIVE

To characterize Boswellia serrata gum as a natural excipient.

METHODS

Boswellia serrata gum, paracetamol, distilled water.

RESULTS

The results showed that the extracted gum possesses optimum organoleptic as well as micromeritic and suspending properties.

CONCLUSIONS

It is concluded from the research work that the gum extracted from Boswellia serrata shows the presence of carbohydrates after chemical tests. All the organoleptic properties evaluated were found to be acceptable. The pH was found to be slightly acidic. Swelling Index reveals that the gum swells well in water. Total ash value was within the limits. The values of angle of repose and Carr's Index of powdered gum powder showed that the flow property was good. IR spectra confirmed the presence of alcohol, amines, ketones, anhydrides and aromatic rings. The suspending properties of Boswellia serrata gum were found to be higher as compared to gum acacia while the flow rate of Boswellia serrata gum (1% suspension) was less than gum acacia (1% suspension). The viscosity measurement of both Boswellia serrata gum suspension and gum acacia suspension showed approximately similar results.
