US5002784A - Microwave-assisted natural products ...

The extraction of natural products from material of biological origin is enhanced and accelerated by concurrent contact with extractant medium and exposure to microwave radiation. Normally the extractant medium is selected to be transparent to the microwave and to remain at ambient temperature: however, if some heating of the medium is permissible it may be partially transparent.

Microwave chemistry - Wikipedia

Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid.Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions.
