Objective: research on the process parameters of microwave vacuum drying technology of Jinshao capsule and its manufacturing feasibility. Method: Microwave vacuum drying technology was select to dry the concentrated liquid extraction of Jinshao capsule and to determine the moisture content, the retention rate of paeoniflorin and berberine hydrochloride. Result: Accessories required for microwave drying process with the shorter retention, retaining the active ingredients better. Conclusion: Microwave drying process is suitable for the drying of Jinshao capsule.
