[Methodological studies on equivalent relationship between granule for clinical prescription and clinical decoction of fructus evodiae].
OBJECTIVE
To investigate the equivalent relationship between granule for clinical prescription and clincal decoction by use of fructus evodiae as a demonstrated object.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
