Abstract: The optimum solvent has been selected for the extraction of the total esters (TEs) from the roots ofFerula tenuisecta. The kinetics of the extraction of the TEs from the raw material have been studied and conditions for the chromatographic purification of the preparation have been determined. The optimum conditions for the separation of the TEs have been found by the method of mathematical planning of experimentation.
