[Method of developing alkaloids of different structural types on a thin layer of sorbent].

A new method for developing alkaloids of the piperidine, pyridine, isochinoline, indole, purine and chinoline groups in a thin sorbent layer has been developed. This method is based on the use of the Dragendorf reagent, subsequent disintegration of the stained complex, and chromatogram treatment with a sodium thiosulfate ammonia solution. The method makes it possible to measure quantitatively alkaloids of various structures, using UV-spectrometry after their elution. The relative error is 1.9-5.5% in three parallel measurements.
