The aim of this research was to characterize the volatile fraction of teas, prepared from chamomile sachets marketed in the Rio de Janeiro city, using solid phase extraction and chromatographic techniques. Forty two compounds were tentatively or definitely identified. Among them, nineteen (19) compounds were identified for the first time as chamomile constituents. Believing that the samples were collected from reliable producers and suppliers, the identification of these new volatile compounds could be explained by the selectivity of the volatile fraction isolation process. The samples belong to the chemotype A, in which the main component is the bisabolol oxide A. The compounds 1.8-cineol and linalool presented odour activity values greater than one, being classified as potent odorants. The presence of ascaridole, coumarin and 7-methoxycoumarin denotes that this beverage must be consumed with care by specific groups like pregnant women and people that are accomplishing anticoagulant therapy.
