Abstract

The invention relates to the blending extraction process of rhubarb and monkshood in compound Chinese medicine Xiaokening. The blending extraction process of the rhubarb and the monkshood comprises the following steps: mixed powder of the rhubarb and the monkshood is dipped in 6-15 times water for 2-8 hours; and then soak pollution is extracted twice under the assistance of microwave; after extraction liquid is centrifugal and filtered, double extractive supernatant fluids are combined and concentrated till the concentration of drug ingredients is 0.05-0.5g / ml, added with a macroporous resin column for adsorption; firstly, the macroporous resin column is washed with water, and then eluted with ethanol with gradient concentrations; ethanol eluent with 50-80 % of concentration is combined; ethanol is recycled; the blending extractive of the rhubarb and the monkshood is prepared by concentration. The blending extraction process organically combines the microwave assistance extraction process and the macromolecule absorption process and has the technology characteristics of high extraction rate and high purification precision. As the production is safe, reliable, and free from contamination, and the production line composition is simple, the investment is saved.
