胞磷胆碱钠2005版鉴别的翻译:


原文
(1)取本品约10mg,加无水乙醇1ml使溶解,加碘化钾试液2ml与稀硫酸4ml,摇匀,加淀粉指
示液数滴,溶液即显蓝紫色。
(2)取本品的氯仿溶液(1→10)3~4滴,待氯仿挥发后,加2%香草醛硫酸溶液1滴,即显红色,放置,渐
变棕色。
(3)取本品,精密称定,加氯仿制成每1ml中含20mg的溶液,依法测定旋光度(附录Ⅵ E),应显右旋光性。

翻译如下:

1.Transfer the sample about 10mg , dissolve in anhydrous alcohol 1ml, then add potassium iodide solution 2ml and dilute sulfuric acid 4ml ,and mix , add the starch indicator several drops, the color of solution is Blue purple
2. Transfer the sample of chloroform solution 3 to 4 drops, after chloroform to be volatile, add 2% Vaniilin sulfate Solution 1 drop. The color of solution is red, place the solution, the color gradual change palm.
3. Transfer the sample, accurately weighted. Add chloroform to make the solution about 20mg per ml, according to CP 2005, determinate the rotation. It should show right optical rotation.

shake是晃动,stir是搅动,这里要看实验的实际做法是怎么样的了
我觉得在这里面也能看出些我们跟老外思维的不同

用"a couple of drops"也可以

stir比shake好

学习了

I have been reminded many times that “never” say red color, blue color etc. as they are Chinglish (i.e. it should be green grass, not green color grass).  However, happyjyl is expert in this field, I therefore believe that “溶液显**色一般说成a ** color is produced” is a typical expression in chemical testing. (I also search “a red color is produced” in google, and found 4120 results)

“Never” is not absolute.

On the other hand, there may be an alternative for 加淀粉指示液数滴,溶液即显蓝紫色:
add a few drops of starch, then the solution will become indigo blue.
(here I remove the word “color” from “indigo blue color”  suggested by littlewing at 3/F)

一般说about 10mg of the sample 或 5 ml of anhydrous alcohol,而不是把毫克或毫升直接放在后面。
溶液显**色一般说成a ** color is produced.
放置应该是allow to stand,不是place。
制成每1ml中含20mg的溶液应该是to produce a solution of 20mg/ml。
另外你的语法有些问题,你可以看看中国药典英文版。中文版里有的英文版里也都有。

(1)取本品约10mg,加无水乙醇1ml使溶解,加碘化钾试液2ml与稀硫酸4ml,摇匀,加淀粉指
示液数滴,溶液即显蓝紫色。


1.Dissolve about 10 mg sample in 1 mL anhydrous alcohol. Add 2 mL KI solution and 4 mL dilute H2SO4, shake well, then add a few drops of starch solution to a indigo blue color.

本品说sample好不好?

说sample是可以的。淀粉指示液:starch IS。IS即Indicator Solution。

就当你是吸取了。。
Pipet appropriate amounts of solution, measure the absorbance according to XXX. It should have an absorption maximum of 280nm,an absorption minimum of 240nm,and an A280/A260 ratio ranging between 2.1 and 2.2.
