安定注射液的含量测定上海市及浙江省药品标准均采用高氯酸非水滴定法,此法既操作较繁又费时间。我们参考中国药典1977年版安定片的紫外测定法,并加以改进,认为可适用于注射液的分析。现介绍如下。操作方法:精密吸取安定注射液10ml(相当0.05gC_(16)H_(13)ON_2Cl),置125ml分液漏斗中,用氯仿抽提三次,第一、二次各10ml,第三次5ml。合并滤液,置50ml容量瓶中,用氯仿稀释至刻度,摇匀,精密吸取
Determination of stability of injection content Shanghai and Zhejiang Province, pharmaceutical standards are used perchloric acid non-aqueous titration method, this method is both more complicated and time-consuming operation. We refer to the Chinese Pharmacopoeia 1977 edition of azerbaijan UV determination method, and to be improved, that can be applied to injection analysis. Now introduced as follows. Operation method: Precision draw 10ml of stable injection (equivalent 0.05gC_ (16) H_ (13) ON_2Cl), set 125ml separatory funnel, extracted three times with chloroform, the first and second 10ml, the third 5ml. The combined filtrate, set 50ml volumetric flask, diluted to the mark with chloroform, shake, precision drawing
