Study on Bacterial Endotoxin Test of Vinpocetine Raw Material / 中国药房

ABSTRACT

OBJECTIVE:To establish a method for the bacterial endotoxin test of vinpocetine raw material. METHODS:Ac-cording to the bacterial endotoxin test in the Chinese Pharmacopoeia(2010 edition,Ⅱ)Appendix Ⅺ E,the samples with different batches were used for interference test and bacterial endotoxin test by tachypleus amebocyte lysate from 2 manufacturers. RE-SULTSThe vinpocetine solutions with high concentration have interference effect on the agglutination reaction of bacterial endotox-in and the interference can be eliminated by diluting. CONCLUSIONS:The non-interference concentration of vinpocetine solutions is 0.25 mg/ml. Bacterial endotoxin test can be used to control the quality.
