[Separation of novobiocin, isnovobiocin and descarbamyl novobiocin by a thin-layer chromatographic method].

A thin-layer chromatographic method for separation of novobiocin, isonovobiocin and descarbamylnovobiocin using Silufol plates was developed. The method is simple and rapid. It provided clear separation of the components and using of diethyl ether, a simple individual separating solvent. The method allowed determination of novobiocin and the products of its isomerization in the fermentation broth, extracts and dry substances, as well as performance of operative control and regulation of the technological processes of fermentation and chemical purification of novobiocin.
