ABSTRACT

<p><b>OBJECTIVE</b>To study the origin pre-treating and processing integration techniques of Paeonia Radix Alba.</p><p><b>METHOD</b>Different processing integration techniques were adopted and compared with traditional processing techniques to determine drying rate, aqueous extracts and peoniflori content.</p><p><b>RESULT</b>Half-dry slices baked at 100 degrees C for 20 min and steamed at 100 degrees C for 10 min had the highest peoniflori contents. Half-dry slices baked at 100 degrees C 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.</p><p><b>CONCLUSION</b>The origin processing integration techniques of Paeonia Radix Alba lose less active ingredients than conventional processing methods.</p>
