Twenty-eight components, representing 97–99% of oils, were identified. The samples were exclusively sesquiterpenic, dominated in all cases by β-caryophyllene (58.0– 75.0%) and α-humulene (10.1–14.2%); the leaf oil was characterized by a high content of α-copaene (14.2%). Finally, no significant antiradical activity (DPPH method) or inhibitory effect on the soybeen lipoxygenase activity could be observed.
