Abstract:


Background: Microwave assisted modification of polymers has become an established technique for modifying the functionality of polymers. Microwave irradiation reduces reaction time as well as the use of toxic solvents with enhanced sensitivity and yields of quality products.

Objective: In this review article instrumentation and basic principles of microwave activation have been discussed. Microwave assisted grafting of natural gums, characterization of grafted polymers and their toxicological parameters have also been listed. Pharmaceutical applications viz. drug release retardant, mucoahesion and tablet superdisintegrant potential of microwave assisted gums has also been discussed.

Conclusion: An overview of microwave assisted extraction of plant based natural materials has also been presented.

Keywords:
