胞二磷胆碱钠紫外光吸收系数的测定

Determination of Ultroviolet Absorptivity of Cytidine- 5'- Diphosphate Choline Sodium

胞二磷胆碱钠的E_1cm^1%值各文献报道不一,本文使用5台不同型号的紫外-可见分光光度计,测定了意大利、日本和国产本品12批(n=180,s=1.77,CV=0.69%),进一步确认了E_1cm^1%值.

There are different absorptivity of Cytidinte-5'-Diphosphate choline sodium reported in literature. Twelve sample made in different countries such as Italy、Japan and China are determined on five type UV-vis spectrophotometers(n = 180,s= 1. 77, CV = 0. 69%)and a、absorptivity is reported.
