Abstract The essential oil from the flowering aerial parts of Heracleum lanatum Michx. family Apiaceae was obtained by hydrodistillation and analysed by combination of GC RI and GC-MS. The chemical composition of the isolated oil is reported for the first time. Sixty five compounds were identified representing 96.95 of the total oil. The chemical composition of the isolated oil was characterised by a high proportion of monoterpene hydrocarbons 39.42 among which 26946-phellandrene 14.01 sabinene 6.75 and E-26946-ocimene 6.45 were the major compounds. The sesquiterpene hydrocarbons 22.50 represented the second major fraction of the oil followed by the oxygenated sesquiterpenes 21.42. Furthermore antimicrobial activity of the essential oil was evaluated using agar well diffusion method.
