Objective:To develop a saline water salting and drying technology for obtaining the medicinal materials of Angelicae Dahuricae Radix(ADR) in place of origin and avoiding rot and mildew. Method:The slightly wilted fresh ADR was tiled in a container

immersed in the saline water

pressed with stone on the surface

pickled for 1-2 d

discard the saline water

added almost equal amount of fresh saline water

pressed with stone on the surface again

sealed

pickled for a period of time

picked up

soaked and rinsed with water

put in a cool ventilated place to dry

and obtained the medicinal materials of ADR. Result:The medicinal materials of ADR processed by saline water salting and drying technology met all stipulation in the 2015 edition of Chinese Pharmacopoeia about ADR

and the content of nitrite in all samples was lower than 3.3 mg·kg-1(detection limit)

which was in line with the limit index of nitrite in salted products. Conclusion:A new saline water salting and drying technology is developed to make medicinal materials of ADR in place of origin

and no metamorphism has been observed for 2 years later stored in simple warehouse.
