The volatile components from the leaves of Erechtites valerianaefolia (Wolf) DC. were obtained by hydrodistillation and analyzed by GC/MS. A total of 12 compounds, representing 99.8% of the oil, were identified. The dominant compounds were limonene (56.7%), myrcene (12.7%), trans-β-farnesene (10.2%) and 1-phellandrene (8.7%).
