Methods Star anise were extracted from Illicium verum Hook.f. using ethanol and ethyl acetate as solvents. After macron absorption resin layer separation, a kind of white fine powder shikimic acid were obtained. The extracted shikimic acid were determined for chemical qualitative analysis. Writhing test and warm bathing test were performed and observed the mice pain threshold latency and writhing reaction times after giving peritoneal shikimic acid extraction solutions.
