title: [Studies on the extraction of ingredients from Chinese traditional medicine with CO2 supercritical fluid].
abstract: OBJECTIVE
  To study the extraction technology with CO2 supercritical fluid in Chinese Traditional Medicine by extracting the anthraquinones ingredients from Salvia miltiorrhiza and Polygonum caspidatum.
  
  
  METHODS
  Extractions were made under different pressure, temperature, extraction time, entrainer, and the extracts were analyzied by TLC and HPLC.
  
  
  RESULTS
  The technology could be used in extraction and isolation. Under certain conditions, different contents of the extracts could be obtained.
  
  
  CONCLUSIONS
  CO2 supercritical fluid is good at extracing low polarity ingredients, and it shows the evident individurity in extraction of Chinese herb. The technological factors in industrial usage must be thought of all over.
