Abstract:
A lubricant formulation of carbamoylethyl katira and a microwave assisted process for the preparation of the lubricant formulation of carbamoylethyl katira. The lubricant formulation of carbamoylethyl katira having antibacterial activity useful for eye lubricant based formulations, treatment of dry eye disease syndrome, etc.

Claim (Index 6):
A process for the preparation of a lubricant formulation of carbamoylethyl katiraas claimed in  claim 1 , wherein said process comprises of the following steps:\n a) soaking gum katira in water for a time period of 14 to 20 hrs to obtain homogenized gel; b) stirring the homogenized gel obtained in step (a) for 30 to 45 minutes followed by addition of 25 ml of 28% w/v to 44% w/v ice cold sodium hydroxide solution with stirring and additional stirring for 30 min after the addition of ice cold sodium hydroxide to obtain basic reaction mixture; c) adding 11% w/v to 18% w/v of acrylamide to the basic reaction mixture obtained in step (b) with constant stirring for 1 hr to obtain reaction mixture; d) irradiating the reaction mixture obtained in step (c) in a microwave reactor at 450 watt for a time period of 0.5 to 1 min followed by a cooling cycle for a time period of 1 to 2 min at a temperature of 4\u00b0 C. to 10\u00b0 C. in ice bath; e) repeating the step (d) for 3 to 7 times followed by neutralization with dilute glacial acetic acid to obtain neutralized reaction mixture; f) precipitating the neutralized reaction mixture obtained in step (e) with solvents followed by washing with precipitating solvent to obtain precipitate of carbamoylethylkatira; g) filtering and drying the precipitates of carbamoylethylkatira obtained in step (f) to obtain carbamoylethyl katria; h) dissolving 2.5% to 10% w/v of carbamoylethylkatira obtained in step (g) in luke warm sterile water for injection followed by filtration through 0.22\u03bc filtration system; i) sterilizing the lubricant formulation of carbamoylethylkatira obtained in step (h) at a temperature in the range of 121\u00b0 C. to 118\u00b0 C. for a time period of 20 to 40 minutes to obtain sterilized lubricant formulation.
