Sastav eteričnog ulja kamilice s područja Virovitičko-podravske županije | Chemical composition of chamomile essential oil from Virovitica-Podravina County

Croata. Cilj ovog istraživanja bio je istražiti kvalitetu i sastav eteričnog ulja pet uzoraka kamilice od kojih je jedan uzorak bio uzorak ekološki uzgojene kamilice dok su ostali uzorci bili iz konvencionalnog uzgoja s područja Virovitičko-podravske županije. Uzorci kamilice uzeti su od rane i kasne žetve tijekom mjeseca svibnja 2022. godine. Za fizikalno-kemijske analize korištene su sušene cvjetne glavice kamilice. Određivao se apigenin-7-glukozid na HPLC-u i sastav eteričnog ulja koristeći GC-MS. Sadržaj apigenin-7-glukozida kretao se od 0,49% do 0,85%. U eteričnom ulju identificiran je ukupno 71 spoj. Glavni spojevi eteričnog ulja bili su (E,E)-α-farnezen u rasponu od 28,6% do 10,8%, bisabolol oksid B u rasponu od 28,1% do 11,7% i (E)-β-farnezen u rasponu od 14,4% do 10,9%. Osim toga, detektirani su i brojni drugi spojevi koji doprinose bogatom kemijskom profilu ovog eteričnog ulja i koji su važan pokazatelj kvalitete i vrijednosti same sirovine.

Inglés. The aim of this research was to determine the essential oil composition and quality of five chamomile samples, one of which was an organic cultivation sample, while the other samples were from conventional cultivation from Virovitica-Podravina County. Dried chamomile flower heads were used for physico-chemical analyses. Chamomile samples were taken from early and late harvest during the mjonth of May 2022. Dried chamomile flower heads were used for physico-chemical analyses. Apigenin-7-glucoside was determined by HPLC and essential oil composition using GCMS. The content of apigenin-7-glucoside ranged from 0.49% to 0.85%. A total of 71 compounds were identified in chamomile essential oil. The main compounds of the essential oil were (E,E)-α-farnesene ranging from 28.6% to 10.8%, followed by bisabolol oxide B ranging from 28.1% to 11.7%, and then (E )-β-farnesene ranging from 14.4% to 10.9%. In addition, numerous other compounds were detected that contribute to the rich chemical profile of this essential oil and are an important indicator of the quality and value of the raw material itself.
