description The invention discloses a preparation method of radix bupleuri or vinegar-baked bupleurum root formula granules. The preparation method comprises the steps that a, radix bupleuri or vinegar-baked bupleurum root is crushed into coarse particles; b, the coarse particles are continuously input into a continuous dynamic countercurrent extraction machine, hot water is reversely added for continuous dynamic countercurrent extraction, and an extracting solution is collected; c, the extracting solution is filtered and subjected to high temperature sterilization, and filtrate is concentrated under reduced pressure to form a clear paste; d, excipients are added to the clear paste for dissolution, and spray drying is performed to obtain dry extract powder; and e, preparation excipients are added to the dry extract powder, and dry granulation is performed to obtain the radix bupleuri or vinegar-baked bupleurum root formula granules. The preparation method adopts a production process of continuouscountercurrent extraction
