After studying the discipline of chemical components distribution in peony root, it was found that the content distribution of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol was inhomogeneous in different parts of peony root, as same as in different roots belonging to a same plant. Therefore, in order to minimize the effects of different qualities of materials on experimental result, the content changing percentages of four chemical components was chosen as indicators to study processing method of Paeoniae Radix Alba. The processing technique of Paeoniae Radix Alba was put peony roots in the boiled water for at most ten minutes, and cut them into 2-3 mm slices after peeling the root bark, finally dry them in a oven under 55 degrees C, which was similar to the traditional processing method used in Bozhou. And the peeling, boiling and drying methods would affect the contents of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol on several levels.
