Abstract:
OBJECTIVETo investigate the effect of removing bacterial endotoxin in the key processes of Reduning injection.
METHODThe content of bacterial endotoxins was detected by kenitic-turbidimetry and the removal efficacy was studied before and after using 0.8% of activated carbon and ultrafiltration with molecular weight cut-off of 10 x 10(3).
RESULTThe adsorption rate of bacterial endotoxins was 78.7% by using activated carbon, while the removal efficacy of bacterial endotoxins was 99.6% with ultrafiltration membrane at cut-off molecular weight 10 x 10(3).
CONCLUSIONThe key technology can effectively guarantee the safety of Reduning injection.
