Herbal medicinal plants are said to be the nature‘s gift to mankind, since they have been of long age remedies for human diseases. The present study was undertaken to isolate gum from the seeds of Delonix regia linn, to explore its use as a Pharmaceutical exicipient. The isolated gum was evaluated for various Pharmacognostical parameters and physico-chemical characterization. The loss on drying, ash value and microbial load were well within the official limits. Qualitative phytochemical analysis of these extracts revealed the presence of flavonoid, saponins, carbohydrates and tannins in some extracts, The explored result suggest that various bioactive compounds of seed can be used for curing various diseases .This study elucidated the physical, thermal, sorption and functional properties of a gum obtained from the seed of Delonix regia . Scanning electron microscopy (SEM), Particle size analysis, X-ray powder diffraction (XPRD), Differential scanning colorimetry (DSC), and Fourier transmittance infra red (FTIR), were used to characterize the gum sample which can be used further for the formulation development.
