Objective To explore the most appropriate technology for the extraction of analgesic components from Scorpion. Methods The most appropriate technology was screened based on the comparative study between the technology of water decoction and ethanol circumfluence,with the consumed volume of menstruun,concentration and extracting time as the evaluating factors, on the basis of orthogonal design.Results The product of main analgesic components of scorpion, Scorpion protein, was higher, when extracted by the extracting techniques of ethanol circumfluence, than that of water decoction. Conclusion T...
