[The quality control of carbonized cortex moutan].

ABSTRACT

OBJECTIVE: To set up method for the quality control of carbonized Cortex Moutan. METHODS: The optimized processing technology of carbonized Cortex Moutan was selected by the time of blood coagulation. Besides, the contents of tannin, adsorbability, paeonol and peoniflorin were researched. RESULTS: To parch the pieces 5 minutes at the temperature of 22 degrees C was the optimized processing technology. CONCLUSION: This study provides a reference to the institution for the quality standard of carbonized Cortex Moutan.
