Biopolymers are polymers that are biodegradable. The input materials for the production of these polymers may be either renewable (based on agricultural plant or animal products) or synthetic. Natural gums are widely used as emulgents, binders, suspending agents and film formers etc.These natural gums are the byproducts which results from metabolic mechanisms of plants. They are either soluble in water or forms viscous solution after absorption of water. The current study was designed to isolate, purify and characterization of biomaterial obtained from Prunus insititia. The physical, chemical and flow properties of biomaterial obtained from Prunus insititia were conducted and satisfactory results were obtained. Key words: - Prunus insititia, Biopolymer, Swelling index ______________________________________________________________________________ INTRODUCTION The excipients obtained from plant origin are gaining importance in the formulation of various dosage forms like, emulsions, matrix tablets etc. These excipients are eco-friendly and easily available Prunus insititia belongs to the family Rosaceae. The fruit pulp consists of carbohydrate, fats and proteins, minerals. The biopolymer obtained from Prunus insititia can be used in pharmaceutical formulation due to its edibility, biodegradability and biocompatibility. MATERIALS AND METHODS Materials The fruits of Prunus insititia were collected from the local market of Dehradun, India. Dimethyl Ketone was procured from SD fine chemicals (Mumbai, India). All other chemicals used were of analytical grade.
