The major components found in the oils of specimens B, collected at São Sebastião da Boa Vista, State of Par a, were 1,8‐cineole (23.9%), borneol (21.8%) and β‐caryophyllene (18.8%). The oils of specimens C and D, collected at Melgaço, Marajó Island, State of Pará, were dominated by α‐pinene (51.1%; 14.5%), 1,8‐cineole (16.5%; 36.7%), limonene (15.0%; −) and β‐pinene (10.3%; 7.9%), respectively.
