Abstract
The volatiles from leaves and fine stems of Hyptis mutabilis collected in the Amazon region were obtained by hydrodistillation and analyzed by GC/MS. The major components identified in the two especimens collected in the localities of Lago Grande and Retiro das Pedras, state of Amapá, Brazil, were thymol (37.4%), p-cymene (19.3%) and γ-terpinene (16.6%) in the former, and δ-3-carene (25.5%), terpinolene (24.7%) and globulol (11.9%) in the latter. The main compounds found in a third specimen, collected in the city of Belém, state of Paré, Brazil, were β-caryophyllene (18.4%), 1,8-cineole (16.8%) and bicyclogermacrene (12.6%). A fourth specimen, collected in the locality of Porto Almendra, Peru, was found to be rich in (E)- and (Z)-methyl cinnamate (70.0% and 9.8%, respectively).
