THE FATTY ACID AND MINERAL COMPOSITION HERBS PICRIS HIERACIOIDES L.

As the object of the study, the herb of Picris hieracioides L., the family of the Asteraceae, widely grown in the middle belt of the European part of Russia, was chosen. Picris hieracioides L. has antioxidant, anti-inflammatory, antibacterial, cytostatic activity. However, its chemical composition has not been studied sufficiently.Biologically active substances responsible for these types of pharmacological activity are not established. The purpose of this study was to study the fatty acid and mineral composition of the herb Picris hieracioides L., harvested in the Kursk region in 2016 during the flowering period of the plant. Gas chromatography / mass spectrometry identified 16 fatty acids, with long chains of from 12 to 24 carbon atoms. Fatty acids are represented by saturated and unsaturated fatty acids, among which saturated (53.42%): palmitic (2479,38 mg/kg) and myristic (867,79 mg/kg). Unsaturated fatty acids are dominated by polyunsaturated fatty acids: linoleic (1543,87 mg/kg) and linolenic (2354,65 mg/kg). The study of the mineral composition by the method of emission spectral analysis showed the presence of 25 mineral elements. Among the macroelements is dominated by potassium. Among the trace elements, a high content of Cu, Zn, Ba, Mn, Sr, Ti, Fe, B, Al, Si is noted. It was found that the content of lead does not exceed the maximum permissible concentration for tea and herbal raw material.
