AB  - Ionic liquids (ILs) solutions as solvents were successfully applied in the 
      microwave-assisted extraction (MAE) of polyphenolic compounds from medicinal 
      plants. ILs, its concentration and MAE conditions were investigated in order to 
      extract polyphenolic compounds effectively from Psidium guajava Linn. (P. 
      guajava) leaves and Smilax china (S. china) tubers. The results obtained 
      indicated that the anions and cations of ILs had influences on the extraction of 
      polyphenolic compounds as well as the ILs with electron-rich aromatic pi-system 
      enhanced extraction ability. Under the optimized conditions, the extraction 
      yields of the polyphenolic compounds were in the range of 79.5-93.8% with 
      one-step extraction, and meanwhile the recoveries were in the range of 85.2-103% 
      with relative standard deviations (R.S.D.s) lower than 5.6%. Compared to 
      conventional extraction procedures, the results suggested that the proposed 
      method was effective and alternative for the extraction of polyphenolic compounds 
      from medicinal plants. In addition, the extraction mechanisms and the structures 
      of samples before and after extraction were also investigated. ILs solutions as 
      green solvents in the MAE of polyphenolic compounds from medicinal plant samples 
      showed a great promising prospect.
