本品为猪眼球及猪甲状腺经双酶水解提取精制而成的灭菌溶液,每支2毫升含化合碘为0.06～0.10mg之间。本品质量标准按一九七七年版药典法检查。我厂试制本品时,感到中国药典一九七七年版所采用的方法已有三十多年之久,测化合碘之方法操作复杂,尚需用高温熔炉、驱溴等步骤,使初学者不易掌握。我们采用比色法,其基本原理与中国药典法相似,即在强硷存在下使其炭化,然后在酸性下加亚硝酸钠使碘氧化成碘分子,溶于氯仿进行比色。经过试验对比,认为此法比较稳定,而且操作简单、迅速、
This product is porcine eye and pig thyroid by two enzymes extracted from the purification of sterile solution, each containing 2 ml of iodine between 0.06 ~ 0.10mg. This product quality standards by the version of Pharmacopoeia 1977 inspection. I plant this product trial, I feel the Chinese Pharmacopoeia 1977 version of the method used for more than 30 years, the method of measuring iodine complex operation, still need to use high temperature furnace, bromine and other steps to enable beginners Not easy to grasp. We use the colorimetric method, its basic principle and the Chinese Pharmacopoeia similar to that in the presence of strong base to make it carbonated, and then added sodium nitrite under acidic iodine oxidation of iodine molecules, dissolved in chloroform for colorimetric. After the test comparison, that this method is relatively stable, and the operation is simple and rapid,
