A total of 53 volatile compounds were identified from British Pure Chamomile Oil, accounting for 89.85% of its volatile components. Among them, there are 6 alcohols, 5 acids, 2 aldehydes, 29 esters, 4 ketones, and 7 alkenes; the main components are 3-methyl-2-butenoic acid hexyl ester, (E ) – rosinol, amyl butyrate, butyl tiglic acid, butyl-3-methyl-2-butenoic acid, rosinone, isoamyl isobutyrate, artemisinone, hexyl isovalerate , Myrtle aldehyde, hexyl acetate, pinene and other compounds. The chamomile plant contains azulene that has only been detected in German chamomile. The German Pure Chamomile Oil is dark blue, which is due to the fact that in the process of distillation and extraction, the natural components of the plant are mixed with steam to produce a kind of “blue chamomile oil hydrocarbon” (matricaria), which shows a rare blue color. Other chamomile oils vary in color.
