The essential oil obtained by hydrodistillation from the aerial parts of Brachyapium dichotomum (L.) Maire (Apiaceae), was analyzed by GC-MS for the first time. Sixty-two compounds were detected, accounting for 96.1% of the total oil, which is characterized by a high content of hydrocarbons derivatives of mono- and sesquiterpenes (80.3%). The main constituents were α-pinene (36.5%), germacrene D (17.9%), dill apiole (6.7%) and myristicin (3.5%).
