[Determination of the kanamycin B content of kanamycin preparations by column chromatography]. / Opredelenie soderzhaniia kanamitsina B v preparatakh kanamitsina metodom kolonochnoi khromatografii.

ABSTRACT

Kanamycin B content in kanamycin preparations was determined with column chromatography and PMR spectroscopy. It was shown that coincidence of the results obtained with both the procedures in analysis of the preparations subjected to additional recrystallization was satisfactory. With the use of nonrecrystallized preparations the admixtures interfered with the results in using the developed procedure.
