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