Identification

1. Into 10mg of the substance to be examined,

add 2ml of water for dissolving and 3ml of

hydroxylamine hydrochloride solution, shake

well, and allow to stand for 3min. Add 1ml of

acid ferric ammonium sulfate, shake well, and

then the solution shows red brown.

2. Add water to dilute 20mg of the substance

to be examined to 100ml, accurately pipette

5ml, and dilute with water to 50ml, to obtain

solution with concentration of 20ug/ml with

water. The maximum absorption should exist

at 293nm, and the minimum absorption should

exist at 241nm.

3. In the chromatogram of the assay, the retention

time of the major peak in the chromatogram

obtained with the test solution corresponds

to that of the major peak in the chromatogram obtained with reference solution.

4. The infrared spectrum of the substance to be examined corresponds to that of the reference spectrum.
