Study On Extracting Effectual Component From Vegetal Cell By The Method Of Microwave Pretreatment

The traditional Chinese medicine is one of the important cultural heritage of our country. It is the important link of producing the Chinese patent drugs and production modernization of traditional Chinese medicine to draw traditional Chinese medicine composition. The industry of traditional Chinese medicine in our country is numerous and mostly use traditional extracted manufacture with water or organic solvents. These technics have many disadvantages, such as heavy consumption efficiency, many impurity, little producing rate and resources can't be fully utilized. So it is important to develop the high梕fficient extracted technics and accelerate the process of the modern production of traditional Chinese medicine, effectively exploit and utilize the resources of Chinese herbal medicine in our country.The method of microwave pretreatment is taken in this paper, which use microwave radiation to destroy cell's structure of plants before traditional extraction in dry or half-dry state. Because microwave deals with materiel which is just wetted by vaporized solvents, microwave is nearly all absorbed by the materiel. The treatment time is only several decades seconds. Because the disposal time is short, the destroy of microwave to target outcome is light and the extraction effect is good. Extracting effectual composition from plants by this method, the temperature of vaporizing is lower in process of microwave, which resolve the problem that microwave extraction is only suitable for extracting outcome of thermal stability.In order to prove the method of microwave pretreatment, this method is takenin this text to extract the effectual composition from Flos lonicerae, Cassia cortex and Gonkgo biloba flavone glycosides. It is show that compared with the traditional method, the method of microwave pretreatment can not only shorten the time of extraction but increase the rate of extraction of effectual composition. Compared with the method of microwave assistant studied more at present, the method of microwave pretreatment requires less to equipment and is easier to realize industrialization.
