New technology for extracting natural active substances of lucid ganoderma sporophore at normal temperature

The invention relates to a new technology for extracting natural active substances of lucid ganoderma sporophore at normal temperature. The technology comprises the following steps of lucid ganoderma sporophore pretreatment, superfine grinding, ultrasonic circulation extraction, vacuum concentration and vacuum freeze-drying, so as to obtain the natural active substances of the lucid ganoderma sporophore. Superfine grinding and ultrasonic circulation extraction technologies are effectively combined, so that the natural active substances of the lucid ganoderma sporophore are good in dissolubility and can be extracted at normal temperature, small influences are generated to the active ingredients of lucid ganoderma, the extracted active ingredient content is high, the extraction efficiency is high, and energy consumption is low. During the ultrasonic circulation extraction of ultrasonic circulation extraction equipment, an ultrasonic field is fixedly distributed, and materials are circulated, so that the ultrasonic field is uniformly applied to the flowing materials, thus, the material treating amount under the action of the ultrasonic field can be increased to the maximum extent.
