临床上常用的右旋糖酐注射液,有含糖(即含5%葡萄糖)和含盐(即含0.9%氯化钠)两种规格。对注射液中右旋糖酐含量的测定,中国药典1977年版是用重量法,即测定注射液中(含糖或含盐一样)不挥发物的总重量减去用化学法测得的其中葡萄糖(碘量法)或氯化钠(银量法)的含量,即可折算出右旋糖酐的百分含量。英国药典1973年版是旋光法,即先测出右旋糖酐注射液(含糖或含盐)的总旋光度,再减去用化学法测得的其中葡萄糖或氯化钠的旋光度,再折算出右旋糖酐的百分含量。国内已有人对这
Dextran injection commonly used clinically, there are sugar (that contains 5% glucose) and salt (that contains 0.9% sodium chloride) two specifications. Determination of dextran injection, Chinese Pharmacopoeia 1977 edition is the gravimetric method, which is measured in the injection (the same as sugar or salt) non-volatile matter total weight minus the chemical method in which glucose (iodine France) or sodium chloride (silver method) content, you can convert the percentage of dextran. The 1973 edition of the British Pharmacopoeia is the optical rotation method, which is to first measure the total optical rotation of dextran injection (containing sugar or salt), minus the optical rotation of the glucose or sodium chloride measured by the chemical method, and then dextran Of the percentage.
