Abstract: The basic principles of the continuous countercurrent extraction are reviewed. The apparatuses of trough type, spiral type, folded type are introduced. The present application of the continuous countercurrent extraction in fruits and leaves is also described. Finally, the union of the continuous countercurrent extraction, the microwave-assisted extraction and the ultrasound- assisted extraction is discussed. And the assumption, union of multifrequency ultrasound and continuous countercurrent, union of microwave and continuous countercurrent, the union of the three extraction technologies was advanced.

Key words: continuous countercurrent extraction, apparatus, vegetable ingredient, union
