[The application of microwave energy in preparation of herbal drugs. 2].
On the basis of various plant organs the relation between the used microwave energy and the drying processes, temperatures of the surface and the interior of the drying materials as well as the remaining moisture in the drugs was investigated. Leaf, flower and herb drugs showed a similar drying behaviour. Plant material of high humidity, e.g. meaty fruits or roots, should be dried by means of pulsed microwave application to avoid too high temperatures. In almost all investigated drugs microwave drying resulted in a lower remaining moisture than air drying. The effect of microwave irradiation on carbohydrates, fats and proteins in plant materials was preliminarily investigated.
