Abstract Hyptis glomerata leaf, inflorescence and stem oil, obtained by steam distillation, were analyzed by GC/MS. A total of 19 compounds were identified, and the major constituents were Î²-caryophyllene (leaf 14.3%; stem 8.6%), Î³-cadinene (around 14% in all parts), guaiol (leafs 10.7%; inflorescence 9.4%), c/s-calamenene (stem, 11.4%) and globulol (inflorescence, 16.8%).
