The invention relates to an extraction process of effective constituents of radix scutellariae, which is characterized in that the technical process includes: the crushing of radix scutellariae, the three-tank type dynamic counter flow extraction, the filtration, condensation and impurity removal of extracting solution, as well as post-extraction processes such as drying. The process overcomes the defects of large menstruum consumption, long extraction time, high energy consumption and low extraction rate of the traditional single-tank extraction process, and adopts the tank cluster series connection mode to extract the effective constituents in the radix scutellariae, thereby fully utilizing the concentration difference between the effective constituents of the extracted menstruum and the medicinal material for recycling the extracting solution, therefore, the method has advantages of small menstruum consumption, short extraction period, high extraction rate and non pan-stick during extracting ...
