Abstract: Background: Natural polymers are widely used as excipients in pharmaceutical formulations. Natural based excipients have various advantages such as non-toxicity, less cost, biodegradeable and easily available. Objective: Review Article involves the study of extraction and characterization of albiza zygia extracted polymer gum as excipient of pharmaceutical. Material and Methods: Methods which are used for the extraction of Albizia zygia derived polymer was based on water extraction method. The various parameters for the characterization of Albizia zygia are:-test for purity, ash value, behavior for solubility, pH, surface tension, swelling index, viscosity to check flow property, particle size, loss on drying, bulk density, bulkiness, powder flow property, etc. Result: The derived gum which is extracted have a good solubility in water which is warm and poor solubility in different organic solvents. The colour of polymer was reddish brown having a good flow properties with pH,i.e.6 Conclusions: It is concluded that the percentage yield of extracted polymer was quite good therefore it is considered that the extracted polymer is used as a good source of mucilage as well as good pharmaceutical excipient in different dosage form.
