Evaluation of Delonix regia Raf. endospermic mucilage as tablet binder.

Delonix regia is tropical tree found widely in India. Seeds of the plant contain glucomannose hence attempt to evaluate the seeds for suitability as tablet binder is considered. Seeds collected from dried pods of D. regia were used for preparation of mucilage. The mucilage obtained was used for preparation of calcium carbonate tablets (Formulation B). The tablets were evaluated for Hardness test, Friability Test and disintegration time and results were compared with standard calcium carbonate tablets (Formulation A) prepared using 5%w/v starch paste as binding agent. Hardness of test formulation was found to be 6.0 kg/cm 3 , the friability loss was just 0.26% and the disintegration time was 7 min. The properties were compared with standard formulation A. The results indicate that endospermic mucilage obtained from D. regia seeds possesses comparable binding properties.
