葡萄糖制剂的含量测定,各国药典均采用旋光法。一般基层单位因限于条件,往往采用碘量法来测定,但普遍反映采用該法操作条件难于掌握,易造成較大的誤差。本文报道有关碘量法测定葡萄糖含量的条件的一些試驗,并将結果与用旋光法测得值进行了对比。实验部分一、药品及試液葡萄糖(比旋度为+53°) N/10碘溶液,N/10硫代硫酸鈉溶波及淀粉指示液等,均按中国药典(1953年版)附录配
Determination of the content of glucose preparations, pharmacopoeia in all countries are using optical rotation method. General grassroots units due to conditions, often using iodometric method to determine, but generally reflect the use of the law operating conditions difficult to grasp, easy to cause greater errors. This paper reports on some of the conditions for the determination of glucose content by iodometry and compares the results with the values measured by polarimetry. Experimental part A, drugs and test solution glucose (specific rotation + 53 ° N / 10 iodine solution, N / 10 sodium thiosulfate solution and starch indicator solution, according to the Chinese Pharmacopoeia (1953 edition) appendix
