The invention provides a preparation method, application and application of an oral tablet of tuckahoe ethanol extract, and a preparation method of an oral tablet of tuckahoe ethanol extract, which includes the pretreatment of tuckahoe and the ultrasonic extraction of tuckahoe, and is characterized in that: The ultrasonic extraction of Poria cocos includes the following steps: S1: adding an extractant to the pretreated Poria cocos for extraction; S2: at room temperature, using a frequency of 26-40KHz for extraction, and routinely filtration after the extraction is completed to obtain an extraction solution; S3: step S2 The obtained extraction solution was concentrated in vacuum at 60°C to obtain an extract concentrate; S4: using the extract concentrate to prepare a chewable tablet of the Poria cocos extract; using the ultrasonic extraction method, the astilbin in the Poria cocos was extracted through an ethanol solution, By controlling the concentration of ethanol, the ratio of material to liquid and the extraction time, the extraction rate of astilbin in the extract of Poria cocos is improved, the solvent is saved, and the operation is simple, which lays the foundation for mass production in the future. |
