To provide new ideas for the technology and equipment development by means of reviewing the research status of the vacuum extraction from traditional Chinese medicine(TCM). Through analysis and statistics of the literature

contrast vacuum extraction process with other extraction technology

analyses the advantage and problems of the vacuum extraction

providing thought for the application of vacuum extraction equipment and the development and improvement. Vacuum extraction can be extracted in lower temperature at the same time guarantee the dynamic

improved the extraction yield of heat sensitive drugs

decrease types of impurities dissolution

etc. Vacuum extraction in the application of TCM compound and the drug efficacy of the vacuum extraction should be further research. Vacuum extraction has unique advantages in the TCM extraction

based on the characteristics of drug itself

selecting suitable vacuum extraction process

and can be applied to practical production.
