Experimental part. 
The chemical composition of the essential oil was studied by chromato-mass 
spectrometry on a gas chromatograph GC-MS-QP2010 (Shimadzu, Tokyo, Japan). 
Qualitative analysis was based on comparison of retention times, indices, and mass 
spectra with corresponding data from the literature and NIST/FFSNC mass spectrum 
computer libraries. 
Vegetable raw materials. The raw material of 
F. persica
was harvested during the 
fruiting period on July 20, 2021 in the Republic of Azerbaijan (Jangi village, Gobustan 
district; 40⁰30'03.04'' C 49⁰15'33.11'' B 356 m a.s.l.). 
Obtaining the sum of biologically active substances: 2 kg of finely ground air-dried 
roots of the part were extracted three times with ethyl alcohol (≥ 99% Merck KGaA, 
EMD Millipore Corporation) for three days. 
The extract was filtered off, the alcohol was distilled off in a water bath using a 
rotary evaporator. Residue 146 g dark brown resin. Yield, 7.3% (weight method). 
60 g of the total extractives were subjected to chromatographic separation on a 
column with neutral alumina II degree. From fractions 22-30, eluting with a mixture of 
hexane, an essential oil with a pungent odor was obtained. 
The discussion of the results.
