Objective: To optimize the processing technology of Panacis Quinquefolii Radix. Method: On the basis of actual production

four factors in the rinsing and softening process were examined

that is

rinsing time

rinsing interval

rinsing water amount and softening time.The three levels were set in every factor

and the experiments were arranged with orthogonal design.The optimal rinsing and softening conditions were screened on the basis of qualified product percentage and the total saponin content. Result : The optimal processing conditions are as follows:the rinsing time is 3 hours

the rinsing interval is 30 minutes

the amount of water used is four times of weight of the medicinal materials

and the softening time is 50 seconds with 2 450 MHz microwave. Conclusion :The Panacis Quinquefolii Radix qualified product percentage and the saponin content is high with the aptimal processing.
