Multi-stage countercurrent extraction (MCE) as a novel extraction technique combines circulatory dynamic extraction and continuous countereurrent extraction.The MCE method offers a high extraction yield and is considered to save time and reduce consumption of both energy and solvent [1-3].Furthermore,the concentration difference between the solid phase and the liquid phase in different extraction vessels can be maintained as constant as possible during the MCE.Consequently,the use of MCE method can increase extraction efficiency and obtain a rapid and complete extraction ofbioactive compounds from herbs.
