Abstract: OBJECTIVE To establish a method of detecting bacterial endotoxin(BET)in procaine hydrochlo-ride injection, and to explore the feasibility of excluding interferentail factor of limulus test by extraction.METHODS ; After sodium hydroxide changed procaine hydrochloride into procaine,and chloroform extracted procaine limulus test was performed. RESULTS 15 batchs of procaine hydrochloride injection were detected. The quantity of BET in each batch was less than 0.25EU·mL-1 and their BET pollution degree were described truly. CONCLUSION Extraction excluding the interferentail factors of limulus test could widen range of application of BET exammatron.
