title: [Study on microwave-assisted extraction technology for active ingredients in different parts of traditional Chinese medicine].
abstract: OBJECTIVE
  To study the optimization process of microwave-assisted extraction for active ingredients in different parts of TMC.
  
  
  METHODS
  Using the uniform design, the optimization processes of microwave-assisted extraction for Flavonoids and Paneonolum in Bidens and Cortex Moutan were gained.
  
  
  RESULTS
  The optimization process of extraction for Flavonoids in Bidens can be described as following: microwave power was 850 W, radiation time was 30 min, solvent concentration was 40%, solvent volume was 13 times as the proportion of raw material, and dipping time was 60 min. The optimization process of extraction for Paneonolum in Cortex Moutan has also been gained which could be shown as following: 340 W as microwave power, 20 min as radiation time, 85% as solvent concentration, 1:5 as the proportion of raw material to solvent, and 30 min as the dipping time.
  
  
  CONCLUSIONS
  These can prove it reasonable to get active ingredients in Bidens and Cortex Moutan with microwave-assisted extraction technology.
