[Research on extracting process for Fengshitongbi capsules].
OBJECTIVE
The optimal extraction technology of Fengshitongbi capsule was investigated in this study.


METHODS
Orthogonal tests were employed for optimum of extraction technology, the determination of the contents of Chlorogenic acid and Sinomenine were gained by HPLC and TLC-scanning respectively.


RESULTS
Six volume of water,extracting 3 times with half an hour each time, and seven volume of 70% ethanol, extracting two times with one and a half hour each time were considered the optimum extraction technology of Flos Lonicerae and Caulis Sinomenii as well as Rhizoma Smilacis Glabrae respectively.


CONCLUSIONS
The considerable extraction rate of active components in the drugs is achieved by applying the selected technology.
