title: Content and composition of the essential oil of Chamomilla recutita (L.) Rauschert from some European countries.
abstract: Variations in the essential oil composition of Chamomilla recutita (L.) Rauschert from different European countries were determined. A total of 39 components were identified, representing over 92% of the total oil yield. The principal biologically active compounds in chamomile oils were bisabolol oxide A (3.1-56.0%), alpha-bisabolol (0.1-44.2%), bisabolol oxide B (3.9-27.2%), cis-enyne-bicycloether (8.8-26.1%), bisabolon oxide A (0.5-24.8%), chamazulene (0.7-15.3%), spathulenol (1.7-4.8%) and (E)-beta-farnesene (2.3-6.6%). In 8 chamomile samples from 13, bisabolol oxide A (27.5-56.0%) was predominant (among them in three Estonian samples). alpha-Bisabolol (23.9-44.2%) was predominant in the samples from Moldova, Russia and the Czech Republic. The sample from Armenia was rich in bisabolol oxide B (27.2%) and chamazulene (15.3%). The oils were obtained in yields of 0.7-6.7 mL kg(-1) and the minimum limit of 4 mL kg(-1) stated by the European Pharmacopoeia was exceeded only in 13 samples from 13 analysed drugs.
