摘要
<p><b>OBJECTIVE</b>To establish the processing method of fructus evodiae and its standard for quality control, toxicity aspects and pharmacodynamics were carried out at the same time.</p><p><b>METHOD</b>In the studies of processing techniques, the optimized technical parameters were determined by the contents of evodiamine and evodine. And the acute toxicity and pharmacodynamics were studied by rats.</p><p><b>RESULT</b>The process was that the liquorice-processed fructus evodiae was wetted by liquorice decoction by sixth of raw fructus evodiae (V/W) and fried below 230 degrees C. The method of detecting the contents of evodiamine and evodine was that Alltima ODS C18 (4.6 mm x 250 mm, 5 microm); mobile phase acetonitrile-water-tetrahydrofuran-phosphoric acid (51:48: 1: 0.05); column temperature 25 degrees C; mobile rate 0.8 mL x min(-1); wave length 225 nm. The toxicity experimentation show that rats didnt show any notable changes after affused the raw material and the processed fructus evodiae's decotion 40 g x kg(-1) b. w. at one time seven days constantly. The analgesic effect was observed after 0.6 g (material) x kg(-1) (weight) b. w.</p><p><b>CONCLUSION</b>The toxicity of the raw material and the processed one were low and the liquorice-processed fructus evodia analgesic effect was good.</p>

<p><b>OBJECTIVE</b>To investigate the equivalent relationship between granule for clinical prescription and clincal decoction by use of fructus evodiae as a demonstrated object.</p><p><b>METHOD</b>Compared the equivalent ratio relationship of granule for clincal prescription and clincal decoction by determination of evodiamine, rutaecarpine, evodine, total alkaloids and dried extract ratio as markers, ten batches reference decoctions were prepared according to clinical usage as evaluation standards, common-use processed fructus evodiae products, such as salt-processed fructus evodiae, liquorice-proccesed fructus evodiae, as researching objects, and finally validated by pharmacological trials.</p><p><b>RESULT</b>Equivalent ratios of granule for clical prescription to clincal decoction are about two in all processed products, and the pharmacological evaluation showed no siginificant difference in this ratio.</p><p><b>CONCLUSION</b>This equivalent ratio model could be referenced in the production. But, it must be noticed that different herbal medicines perhaps have different equivalent ratio, which should be studied further according to its techniques and production conditions, and finally need to be revalidated by clinical trial.</p>
