Study on method of Paeonia Radix Alba producing and concocting integration processing

Objective: To study the origin pre-treating and processing integration techniques of Paeonia Radix Alba. Method:Different processing integration techniques were adopted and compared with traditional processing techniques to determine drying rate,aqueous extracts and peoniflori content. Result: Half-dry slices baked at 100 ℃ for 20 min and steamed at 100 ℃ for 10 min had the highest peoniflori contents. Half-dry slices baked at 100 ℃ for 20 min had the highest content of aqueous extracts. Products processed with conventional method and sulfur-fumigation had the lowest content of aqueous extracts. Conclusion: The origin processing integration techniques of Paeonia Radix Alba lose less active ingredients than conventional processing methods.
