For calcium Weigh and powder 20 tablets. To a quantity of the powder containing the equivalent of 50mg of calcium add 50ml of water and 5ml of hydrochloric acid. Heat the dispersion gently to boiling and continue to boiling for about 2 minutes. Allow to cool and add 50ml of 0.05m disodium edetate VS. Neutralise the solution using 2m sodium hydroxide, add 10ml of ammonia buffer pH10.9 and 50ml of water. Titrate the excess of disodium edetate with 0.05m zinc chloride VS using mordant black Ⅱ solution as indicator. Each ml of 0.05m disodium edetate VS is equivalent to 2.004mg of Ca.
For colecalciferol Carry out the following procedure protected from light. Weigh and powder 20 tablets. Carry out the method for liquid chromatography, Appendix Ⅲ D, using the following solutions. For solution (1) shake a quantity of the powdered tablets containing 0.1mg of Colecalciferol with about 170ml of methanol (90%) for 5 minutes and then mix with ultrasound for 5 minutes, dilute to 200ml with methanol (90%), mix, centrifuge and filter through a glass-fibre filter(Whatman GF/C is suitable).Solution(2) contains 0.00005% w/v of colecalciferol EPCRS in methanol.
The chromatographic procedure may be carried out using (a) a stainless steel column (10cm?4.6mm) packed with stationary phase C(5μm)(Hypersil 5 ODS is suitable),(b) a mixture of 3 volumes of water and 97 volume of methanol as the mobile phase with a flow rate of 1 ml per minute and (c) a detection wavelength of 264nm.Inject 50μm of each solution.
Calculate the content of C27H44O in the tablets using the declared content of C27H44O in colecalciferol EPCRS.
化验
因为钙秤重而且搽粉于 20个平板。 对包含钙的等同于 50个毫克的粉的量增加 50 毫升的水和 5 毫升的 hydrochloric 酸。 逐渐地加热散布到沸腾的而且跟煮沸继续大约 2 分钟之久。 允许冷却而且增加 50 毫升的 0.05m 不憎恶 edetate 和中性化比较解决使用 2m 钠氢氧化物, 增加氨缓冲 pH 10.9 和 50 毫升的 10 毫升的水。 相对以尖酸的黑色Ⅱ解决作为指示物用 0.05m 锌氯化物滴定不憎恶 edetate 的过度。 0.05m 不憎恶 edetate 的每毫升相对对 Ca 的 2.004个毫克是相等的。
因为 colecalciferol 实行，下列的程序从光保护了。 秤重而且搽粉于 20个平板。 为液体的套色版，附录Ⅲ D 实行方法,使用下列的解决。因为解决 (1) 摇动用甲醇 (90%) 的大约 170 毫升包含 Colecalciferol 的 0.1个毫克 5 分钟，然后和超声波混合在一起 5 分钟以来的被搽粉于的平板的量, 经过一个玻璃-纤维过滤器对和甲醇 (90%) ，混合，离心分离机和过滤器的 200 毫升冲淡.(华特曼纸 GF/C 是适当的)解决 (2) 在甲醇中包含 colecalciferol EPCRS 的 0.00005% w/v 。
色析法的程序可能被实行使用 (一) 一个不锈钢柱 (10cm?4.6 毫米) 装满静止的状态 C(5 μ m)(Hypersil 5 ODS 是适当的),(b)如和一分钟 1 毫升的流程率和 (c) 一个 264个 nm 的发现波长的移动状态的水和甲醇的 97 册的一个 3 册的混合。注射每解决的 50 μ m 。
在 colecalciferol EPCRS 中使用 C27 H44 O 的公告内容的平板中计算 C27 H44 O 的内容。
我用我家的金山快译翻到的~~
非常感谢！只是我马上就要用到这篇翻译，所以恳请大家多多帮我翻译一下！谢谢了！！
